THE build, quality and design integrity of today's new cars has been revolutionised over the past decade by the development of computerisation in the design and manufacturing process.

This is not only good news for car buyers but greatly benefits those looking for a used car too. Despite this quality it is important to remember that used cars do need to have been looked after if they are to provide thousands of trouble free miles.

There are many ways to buy a used car but the safest way is from a reputable garage. Main dealers and independent garages such as those belonging to the Retail Motor Industry Federation (RMI) whose members comply with a Code of Practise drawn up in consultation with the Office of Fair Trading, have a huge range of nearly new and used cars.

Main dealers often offer a good supply of carefully prepared late model, low mileage used cars and demonstrators with genuine mileage and services histories. Efficient after-service sales and warranties also ensure peace of mind as do mechanical breakdown, insurance services, hire purchase facilities and servicing back-up.

An independent garage is likely to have on it's forecourt cars spanning a wider age range, from the low mileage to the older more inexpensive models.

"Used car buyers not only make savings on the price of a car but may also benefit from cheaper insurance. Depending on the age of the vehicle improved value can be had by servicing and repairing a car through an independent garage." said Hugh Roberts, Director of the independent garage section of the Retail Motor Industry Federation.

Oil leaks are an obvious sign of age. Inspect drive belts for fraying and cracking. A screeching noise is a sign of a slipping fan belt but it is easy and inexpensive to adjust or repair. The radiator should be free of leaks and the hoses free from damage.

An engine that is not being efficiently cooled could be seriously damaged on a long journey, especially if we have a warm summer.

When you buy from a reputable dealer the car's financial history will have been checked to show there are no outstanding hire purchase agreements on it and that it is neither an insurance total loss or has been stolen. Ask the dealer for written proof that this check has been made. Private buyers can also check the history of a used car by acquiring the appropriate form from the the Citizens Advice Bureau. This service is free.

Before entering into any finance agreement, accepting any warranty or, indeed accepting a used car, make sure you understand and read the documentation before signing them or handing over any cash.
