If you are considering buying from a car auction, you could get a real bargain, but be very wary, particularly if it's your first time at an auction and you don't know much about cars.

Buying a used car this way can be the riskiest method because your usual legal rights may not apply if the seller issues a disclaimer, such as the term 'sold as seen'.

Be careful as auctioneers are allowed (by law) to alter the conditions of sale, often doing this by taking away buyers' rights under the Sale of Goods Act.

It's best to go as a spectator first and see what happens. By attending an auction several times before you start buying, you can get used to the atmosphere and terms such as 'direct cars' which are usually ex-company cars or are direct from the owner.

Always run a check on the vehicle you are interested in, this can save you time and money: a simple 2 minute call to mycarcheck.com (0870 118 1630) or text the registration number to 83600 for a full history via mytextcheck.com and they will inform you if the vehicle is safe to buy.

Beware as not all auctions check vehicles until after you buy, and in many cases not at all.

If you still want to try for a bargain, then know your limit and don't be tempted to bid any higher. The motor trade recommends buying cars between two and five years old.

Check for full service history, this way you can have a better chance of guaranteed mileage.

Check the vehicle registration number with www.mycarcheck.com or mytextcheck.com before you raise your hand to bid.

It's a good idea to take someone with you who knows about cars if you don't.
