If you need to buy replacement parts for your car, one of the first decisions you'll have to make is whether to buy new or used. Buying second hand parts may involve greater risk, but will tend to offer price discounts. By contrast, new parts bought from manufacturers may be more expensive, but these are less likely to result in problems and can be expected to last much longer.

Whether you're buying new or used, it's essential to make sure you buy parts designed for use in the make, model and age of vehicle you drive - otherwise you risk causing serious damage to your vehicle when installing unsuitable parts. If you're hoping to sell your car in the future, you also risk impairing its value by mixing and matching components, and you should think about your car's repair and service history before making upgrades to your vehicle that could cost you in the long term.

Learning how to inspect the condition of parts can also minimise your chances of ending up with an unsuitable component. Being able to demonstrate knowledge of your car's workings could lead to you obtaining discounts and make it easier to track down the specific parts you're looking for, as sellers and technicians will know you're not easily fooled.

More people are now buying parts online, which can be a convenient option to have parts sent directly to your home, but may also involve risk if you're dealing with a seller whose reputation is unknown to you. This can be avoided when buying from established and reputable parts suppliers, being sure to check for warranties and return policies in case something goes wrong.

Not all car parts are suitable for reselling either, and you should think carefully before buying used tyres and other components that typically wear out faster. When buying more expensive car parts, such as engines and transmissions, you should also arrange professional installation at a local service centre to reduce the risk of problems occurring, unless you're a trained mechanic.

All types of car parts can be found online and from parts suppliers, and not only components that are critical for your vehicle's operation. If you're looking for replacement bumpers or car body parts, including doors and bonnets, salvage yards could be the best option, while accessories such as door handles, cup holders and seat covers could improve your driving experience.
