Verooom's simple steps to avoid getting ripped off by cowboy mechanics

Working on car engine

It's fairly common to hear stories of people being fleeced by the local garage or mechanic, but what steps can you take to empower yourself and avoid be caught out by a cowboy?

Here's our 18 top tips to minimise the risk, and hopefully keep you from becoming just another victim.

Look around

Major franchises tend to charge a lot more than small, independent retailers (they have to pay for the snazzy overalls somehow) so it's well worth shopping around for the best price, you could be saving yourself a small fortune!

That AUDI garage could be twice the price of a perfectly reputable local mechanic with more combined years of experience than all of the AUDI mechanics put together!

Beware a growing repair list

Remember what your car went to the garage for, although it's perfectly normal for a mechanic to highlight additional work that may need to be done to your car to keep it running, particularly if it impacts safety, if the list of repairs starts to grow rapidly, you should be very suspicious.

If you're not sure, get a second opinion! If you went to the garage for an interim service and you're now forking out for brand new alloy wheels, tyres and an Eric Cartman shaped air freshener that glows in the dark, it's definitely time to get a second opinion!

Plan Ahead

Don't leave it to the last minute to find a trustworthy mechanic or garage, you should have someone in mind well before your car needs a service, this will save you having to choose one in a hurry.

Make a note of the work that needs doing

Its well worth making a note of any work you need doing and giving a copy to the mechanic before they start. Be sure to keep a copy for yourself as well.

Make sure the work is guaranteed

Before any work starts, make sure all parts and labour are guaranteed. If you don't and something goes wrong it will be entirely at the garages discretion as to whether they put it right.

Use MOT Test Centres

If you need an MOT it's much better to take your car to a dedicated MOT test centre, that way you can be sure your getting a completely unbiased opinion as appose to risking being told your car needs work doing to pass, when it actually doesn't at all.

Empower yourself

Obviously nobody expects you to have a masters degree in mechanical engineering, but a little knowledge goes a long way, so try learning a little about your car.

Even something subtle such as leaving a Haynes car manual on display in your car will suggest you know at least a little about it, and won't be an easy target.

Use a recommended garage

Word of mouth is a priceless resource, so it's well worth asking your friends and family members to recommend a garage where they have received good service and value for money.

Don't pay with cash

Cash is great but what happens when something goes wrong? You've already parted with your money and then if a dispute arises, it's going to be a lengthy and difficult process getting a refund. Luckily, cash is not the only option. If you pay by cheque for example you can always cancel it should a problem arise. You can also pay by credit card as most credit card payments these days are covered against fraud.

Mark your parts

It's well known that some unscrupulous garages will try charging you for parts that were never replaced so, if you already know which parts are due for replacement its worth marking them just to make sure they actually have been. You can also insist on disposing of the old parts yourself.

Record any damage

It's worth making a note or taking photos of any scratches or dents on your car prior to taking it to a garage then, should it have any unfortunate mishaps while it's in their care you will know about it, and have the evidence to prove it!

Do your homework

Don't just take a mechanics word for it, do your homework, you should know exactly when your next service is due, and the schedule for the replacement of worn parts. This information can usually be found in your car manual, log book or the manufacturer's website. Still looking? There are a ton of websites out there offering free and paid car manual downloads, just Google it!

Take a test drive

A good way of making absolutely sure your car has actually been fixed is taking it for a test drive, so don't be afraid to ask BEFORE you shell out any money. A legitimate garage will have nothing to hide and therefore, won't have a problem with your request.

Check the quote for hidden extras

When you get a quote, be sure to check the price is inclusive of VAT, parts and labour, as some dealers may add these later on top of what you think is an inclusive quote. Some really unscrupulous dealers may even do this on purpose in order to catch you out so be very wary.

Don't be afraid to ask questions

When the work is complete, make sure you are given a full receipt, broken down into parts, labour and VAT. If you are not sure about anything on the receipt, don't be afraid to ask questions and if you don't understand the jargon, insist they explain in plain English.

New or reconditioned parts?

Occasionally garages use reconditioned parts, to fix your car as appose to new ones, so it's worth double checking. If they are using reconditioned parts, although perfectly acceptable practice, you should not be paying for new parts.

A stitch in time...

Try not to let car problems accumulate, keeping your car safe by taking it to a qualified technician is essential, so do so in a timely manner. If you know your tyres are due to be replaced, get it done! A blowout could easily cause a fatal accident.

Find an MICP accredited garage

The Motor Industry Code of Practice for Service and Repair was developed by the industry to help motorists find garages that will provide them with a good service.

Any garage undertaking car (or light commercial vehicle) servicing or repair can sign up to the code and agree to comply with its standards, which covers all aspects of garage work from advertising, booking in work, undertaking repairs, staff, invoicing and resolving complaints.

Each garage signed up to the Code agrees to provide their customers:

  • Honest and fair services
  • Open and transparent pricing
  • Work completed as agreed
  • Invoices that match quoted prices
  • Competent and conscientious staff

Top 10 Most Effective Performance Car Modifications

08 December 2009

engine With so many car performance modifications around today, it's difficult to know which ones will give you the best results, and most bang for your buck. Luckily the Verooom team have compiled this run down of the top 10 most effective performance modifications on the market today, in comparison to the relative cost of making each modification.

Due to today's strict emissions and fuel economy standards to which manufacturers have to conform, most new cars bought these days are actually capable of performing far better than they are advertised, and sold to us. So, how can we remove these built in limitations and unleash a cars full potential? Here's a rundown of the top 10 performance enhancing modifications available to us with today's technology. Some are cheap, some are expensive. But which one gives you the most BHP per pound of your hard earned money? Read on to find out in the Verooom Top 10 Most Effective Performance Car Modifications. turbocharger

Turbocharger

Performance gain: Very High (30% to 100% / average 40%)
Installation: Difficult
Cost: Very High (between £2500 and £5000 with fitting)

A turbocharger takes pressure directly from the engine's exhaust system to power a supercharger, which forces more air into the engine resulting in greater air density in the cylinder and in turn, more power.

One disadvantage of the turbocharger is that it causes the engine to run hotter. So If you add a turbocharger to your car, you'll need to find a way to keep the engine cool as well. Many people get around this problem by installing an intercooler, however, this is at significant extra cost.

So, if you have a relatively high budget turbochargers are an incredibly efficient and effective way to get more performance out of your engine, but be prepared to shell out some extra cash up-rating your coolant system.

Advantages: Very high power gain, efficient.
Disadvantages: Expensive and difficult to install, expect to have to up-rate cooling components.
Verooom value for money rating: 6/10

supercharger

Supercharger

Performance gain: Very High (average 46%)
Installation: Difficult
Cost: Very High (between £2500 to £5000 with fitting)

A supercharger, sometimes called a blower, is similar to turbocharger insofar as it acts as an air pump, the crucial difference being a supercharger is a mechanically driven pump whereas the turbocharger uses the power of hot exhaust gases to power the pump.

Because superchargers run straight off the engine, they can increase engine load by up to 30%, meaning technically, they are less efficient than turbochargers. However, they do still have a number of advantages over the turbocharger. They are easier to fit, marginally cheaper and generally do not possess most of the negative handling characteristics of your average turbocharger, offering smoother power gains right across the rev range.

The only downside is they require a lot of space under your bonnet so if you haven't got bags of room in there, be prepared to fit a scoop to accommodate the extra components.

Advantages: Very high power gain, Smooth power gains.
Disadvantages: Not good for small engine bays, puts extra stress on the engine.
Verooom value for money rating: 6/10

nitrous

Nitrous

Performance gain: High (average 25-35%)
Installation: Moderate
Cost: Moderate (around £500)

Nitrous is short for nitrous oxide (N2O). In car engines, as Nitrous gas is heated up in the combustion process, it breaks down releasing additional oxygen and increases the burn rate thus allowing more fuel to enter the combustion chamber.

One side benefit of Nitrous is the cooling effect it has as it rapidly changes from a liquid to a gas. This cooling effect reduces the temperature of the air taken in by 60 degrees F (15 degrees c). Colder air carries more oxygen which is required for combustion to take place - more oxygen means you can burn more fuel.
Though nitrous can create incredible boosts to an engine's horsepower, 20bhp to over 200bhp or more depending on the size of the nozzle jets, it can also increase wear and tear on most of a cars components. In addition, Nitrous is not street legal in many areas and as a result, it is seen mainly on cars modified for racing.

The Nitrous gas itself is released into the engine via a button or switch on the cars dashboard. As the gas burns so quickly you can only expect to get a minute or so of boost per bottle of gas. For most drivers this is not a problem as the Nitrous has such a dramatic power gain, it would be almost impossible to use it for any longer than a few seconds without your car being ripped apart, or even taking off!

Advantages: Affordable, high performance gain, controllable.
Disadvantages: Short lived, bad for the environment, increase wear and tear, illegal in some places.
Verooom value for money rating: 8.5/10

Sway Bars and Control Arms

Sway Bars and Control Arms

Performance gain: N/A
Installation: Moderate
Cost: £100 to £400

So, we know it's certainly possible to improve a cars performance with out and out raw power. This is great if were driving in a straight line all the time, but that's highly unlikely, so what about handling?

A car that handles well enough to take turns at high speeds will almost always win races over cars that just have bags of raw power, but must slow down for turns.

One way to improve a cars handling is to stiffen the suspension. Sway bars and control arms are components of car suspensions that work to counteract body roll and keep the car firmly planted in turns. Adding stronger sway bars and control arms to a car stiffens the suspension, minimizing body roll and allowing it to take corners at higher speeds.

Advantages: Better handling.
Disadvantages: None.
Verooom value for money rating: 8/10

disk brake

Ceramic Brakes

Performance gain: N/A
Installation: Moderate
Cost: Very High (around £5000)

As you increase the power of your car, it inevitably becomes harder to stop. Therefore it may become necessary to replace the stock brakes, particularly if you have drum brakes as appose disc brakes. The problem with most brakes is that they get very hot and when brakes get hot, they lose a lot of their stopping power.

One way around this is to switch to ceramic disc brakes. Unlike metal disc brakes, ceramic disc brakes don't conduct heat very well. This keeps the brakes cool and stopping power strong. Otherwise you might find yourself running out of road!

The only real downside to ceramic brakes is the cost. Although you can pick up ceramic brake pads relatively cheaply, expect to spend the best part of 5 grand upgrading the discs and callipers.

Advantages: Better more reliable and consistent braking.
Disadvantages: Incredibly expensive.
Verooom value for money rating: 2/10

spoiler

Spoiler

Performance gain: N/A
Installation: Easy to Moderate
Cost: Cheap (around £100)

As a car accelerates, it generates lift, much in the same way an aeroplane does to take off. While for the average motorist this isn't a concern, performance drivers know that lift limits the tyres contact with the road and in turn, this means less grip and wasted engine power.

The addition of a spoiler causes the air rushing overhead to push down on the car, stabilizing it and making sure more of the engine's power hits the road. And for even more grip a splitter can be added which has much the same effect but at the front of the vehicle.

Spoilers are a cost effective way of increasing grip giving you more power and control at high speeds, but are absolutely useless on non-performance vehicles.

Advantages: More grip, less wasted engine power.
Disadvantages: Look silly on vehicles that simply don't need them.
Verooom value for money rating: 9/10

integrated circuit

Chipping & ECU Remapping

Performance gain: High
Installation: Easy to Moderate
Cost: Moderate to High (£250 to £1000)

Due to today's strict emissions and fuel economy standards to which manufacturers have to conform, most car engines these days are controlled and regulated by computers which in most cases, actually limit a cars performance to well below its actual capability. There are however a couple of ways you can remove this limit and unlock your cars full potential.

ECU Remapping is a process by which a cars diagnostic port is used to re-program the ECU to get the best possible performance out of your car. When an ECU is remapped, the program that deals with engine performance is basically being fine tuned. This is usually done with 2 objectives in mind. As well as re-mapping the ECU to produce greater power and torque, drivability problems at lower rev ranges such as flat spots and hesitation issues can also be smoothed out, giving the engine more initial torque making a more responsive and enjoyable drive.

Chipping is basically the same as ECU remapping but instead of re-programming the unit you're bypassing it completely. This is often less effective than remapping because every engine runs slightly differently, and mass produced pre-programmed chips don't take into account an engines subtle differences.

The only downside to ECU remapping and chipping is that a cars fuel consumption can dramatically increase. Also, over time, as the car is performing far beyond its originally asserted capability extra stress on the components means you will find they wear out far faster. You can also expect to have your vehicle serviced more often to keep it in tip top condition, sometimes as much as double the normal rate.
One way around this is having several chips or re-maps and switching between them depending on how you intend to drive. For example, you could have an economy setting for running the kids to school, a cruising setting for motorway driving and a sports setting for those weekend track days.

Advantages: Affordable, high performance gain.
Disadvantages: Increases fuel consumption, parts wear out faster, increased frequency of vehicle servicing.
Verooom value for money rating: 9/10

cylinder head

Cylinder Heads

Performance gain: High
Installation: Moderate
Cost: Moderate to High (£500 to £1500)

The majority of modern production engines have only two valves per cylinder, an intake valve to let air in, and an exhaust valve to let exhaust gasses out.

A good way to get more power out of your car is to upgrade your cylinder heads to a set that has four valves per cylinder. The additional intake valve allows more air to enter the cylinder, resulting in stronger combustion, while the extra exhaust valve clears out the engine's waste faster.

Advantages: More power, reverse-able.
Disadvantages: None.
Verooom value for money rating: 7/10

exhaust

Exhaust

Performance gain: Small
Installation: Easy to Moderate
Cost: Cheap to Moderate (£50 to £500)

As we already know, a good way to get more power out of your car is to let more air into the engine which results in stronger combustion. An often-overlooked way to improve performance is to help the exhaust gasses get out of the engine.

The exhaust is an engine's way of exhaling. If it's difficult to exhale, the engine can't work as hard. As most performance modifications are designed to force more air and fuel into the engines cylinders, it becomes important to ensure the engine has the ability to expel the gasses efficiently.

Upgrading a car's exhaust system with headers, wider exhaust pipes and free-flowing mufflers will make it far easier for the engine to expel its waste and therefore increases performance.

Advantages: Affordable, makes the most of other performance modifications.
Disadvantages: None.
Verooom value for money rating: 7/10

cylinder head

Rebore the Engine

Performance gain: Moderate
Installation: Difficult
Cost: Cheap (from £10 per cylinder)

Reboring a car's engine to increases displacement is another, and our final way to improve its power. When an engine is rebored, each cylinder is bored out (made bigger) to give it greater capacity, and then fitted with larger pistons and connecting rods. This increases the cylinders volume, which increases the amount of air and fuel that can fit in the cylinder. More air and fuel means more powerful combustion, and in turn a higher power output for the engine.

Before you even consider a rebore, it's important to check that you can get a gasket, piston with rings and other components to match your chosen bore capacity. A rebore is irreversible and you'll certainly not want to have to do it again. Another thing to consider is that after reboring your engine, it will be necessary to run the engine in again. This process of bedding in could take up to 9000 miles. That's a whole 9000 miles of sensible driving!

If a rebore sounds too scary for you, another option is to use a stroker kit. A stroker kit changes the length of the crank which, when combined with a lower profile piston, increases the capacity of the cylinder.

Advantages: Cheap, good power gain.
Disadvantages: Requires bedding in, not straight forward, irreversible.
Verooom value for money rating: 9/10

Conclusion

Although there are clearly many ways to get better performance out of your car, all with various pros and cons, what gives you most bang for your buck? Well, we think if you're not too worried about servicing your car more regularly, it could be time to get an ECM remap. Affordable, flexible and completely reversible, we think it's the clear winner.

Verooom announce launch date for innovative new "fee free" auction website, VerooomAuction.com

Are you like the millions of people who love to Bid, Buy, and Sell online? Well we created this site just for you!

Verooom, one of the UK's leading providers of alloy wheels, tyres and car servicing has just announced that it will be launching its Online Auction Website, verooomauction.com on the 05th December, 2009.
VerooomAuction.com is slated to offer its members the ability to buy and sell new and used cars, motorcycles, tools, parts, accessories and performance car parts with many items going for a fraction of the retail price.

Those looking for great deals on great products will be able to find them only a click away. This is undoubtedly every buyers dream come true, to get high quality branded items so cheap, and through such an innovative online shopping experience.

A typical VerooomAuction auction works in pretty much the same way as most popular online auction sites but with one major difference. No buying, selling or signup fees! A spokesman from the firm, who also offer ECU re-mapping and MoT testing, said "with online auctions so popular these days, it’s amazing that they are all so expensive to use. We have tried selling on other auction sites ourselves but quickly found the charges for the average business were so high, we just couldn't make a return on our sales. So we decided to create something fun and easy to use for us and our customers, without all of the charges"

Preston Auto Repair Specialists Verooom to Launch New Auction Site

With the buzz over the launch of their new website verooom.com hardly having died down, Verooom, one of the UK's leading providers of alloy wheels, tyres and car servicing has announced that it will be launching an all new Online Auction Website, www.verooomauction.com very soon.

This site will provide the most innovative online shopping experience to buyers from across the world. Buyers will soon be able to buy and sell new and used cars, motorcycles, tools, parts and accessories with many items going for a fraction of the retail price. Those looking for great deals on great products will be able to find them only a click away. This is undoubtedly every buyers dream come true, to get items so cheap through an innovative online shopping experience. Where else can somebody get an AA Micro Travel First Aid Kit for as little as £2.13 or an NGK Sparkplug for just £1.30?

The concept behind this revolutionary site is quite simple. The buyer has to place a bid and wait for the timer to end. If the timer ends and no one bids after him, he will be the auction winner. The lucky bidder may then purchase the item at the final price and have it shipped to them. Winning bidders can pay for items using the highly popular online merchant, PayPal.

Products to be offered at the site will range from cars, car stereos, tools, suspension kits, exhaust back boxes to thousands of performance car parts and vehicle accessories.

Expect to see all names that guarantee quality including: PI, Autocare, Draper, AA, Auto-Plas, Carplan, CT Racing, Kenwood, Alpine, NGK and Champion to name but a few.

Registration on the site is absolutely free, so be sure to log on to the site and get in on the action as well as to remain informed of the actual dates of the launch. The fact that this is a safe, fun, easy and affordable way to buy, makes this site one you cannot afford to miss.
