There are several unwritten rules for car auctions.
This is to ensure that you know some of these, so that you make the right decision and choices.
Some of the Unwritten Rules of Car Auctions It is important that you have some knowledge of auctions, know the auction rules, and have some knowledge of cars.

  It is therefore necessary that you have some knowledge of cars to see where problem areas are.
  

• The most important part is that you should know who put the cars up for auction.
  Are these:
  • Banks or financial Institutions
  • Are they new-car dealers or
  • Independent car dealers

This will give you some idea from where the cars originate.

• A pre-check on the history of the cars, by using the online list, is then possible.
  This would give you the vehicle identification numbers (VINs), and the vehicle's worth and other information.
  

• On arrival at an auction, you have to register, and produce your license as well as pay a small deposit.
  Check with them as there is often an auction fee.
  

• If you were early, some auctioneers would allow you to test drive the vehicle you are interested in.
  This will help you make your decision too.
  

• Make sure that you assess the car thoroughly.
  If you do not have mechanical knowledge, take someone with you.
  Your assessment could include the previous owner.
  The radio stations the person last listened to, or the little things that were left in the glove box will give you a clue of the type of driver used the vehicle.
