The Internet has revolutionised the way we shop, from the small value purchase to high priced items it seems anything can be bought and sold online.

Buying and selling new and used cars through the Internet is now big business. It allows you to not only research your next car but also find the model of your choice for the price you are willing to pay. The car doesn't even have to be for sale in your local area - many online sites will arrange to deliver your car to your (for a fee) or are prepared to transfer it to your local dealership (if they are part of a nationwide chain).

The types of online car sales outlets vary. You can find classified advertisements for used cars from private sellers, to websites of independent local garages, nation wide franchised dealerships, car supermarkets and even importers all at the click of a button. However, such a wealth of information can be confusing and it is important not to get carried away. You should try to refine your search so your results are filtered and of interest to you.

Although the Internet does a great job of bringing the information to you, you must avoid making hasty decisions. Remember that the financial outlay for a car can be significant, and even the best photographs and comprehensive specifications do not remove the need for a closer inspection. A test drive is always a great way of deciding upon your next new car and a visual, physical check of the cars condition is always helpful.

If you are responding to an online classified ad from a private seller then some sites will allow you to purchase online, directly from the seller. Buying a car without physically seeing it or driving it is risky, but if you are confident that the price can justify the risk then proceed. However, stipulate when buying that the V5 logbook must be provided along with proof of ownership and identification. Many of the car supermarkets will also allow you to buy or reserve the car online, usually for a small deposit. This is less risky than buying from a private seller and usually comes with a "cooling off" period meaning you can change your mind.

Dealership websites will generally not allow you to buy online, but they will provide you with all the information you would have found if you had visited their garage, such as the price, mileage, condition etc. You should use the Internet to determine which dealerships have cars of interest and are therefore worth a visit and which do not. This can save you a lot of time and effort.

If you are looking to buy a new car then the manufacturers website is a great place to gain an understanding of price and running costs. Many of the manufacturers sites allow you to "build" your new car to exact specifications, choosing colour, engine size, and luxury add-ons before providing you with an on the road price. You can then take this information to your local dealership and place your order, knowing that you have chosen the car that is right for you without any pressure from the sales person.
