Having been to a few dealer auctions, I can tell you that you better know what you're doing--or know someone who does--if you want to buy an auction car. For one, the environment is very hectic. You won't have enough time to test the cars. You can't drive it, you can't start it. Basically, if you can't tell a good car from a bad by just looking and feeling the paint, don't go. At a dealer auction, you will see cars from dealer trade-ins, from leasing companies, from rental companies, etc.,. Rental cars can be attractive candidates, but for reasons stated above you should stay away from them. For lease returns and dealer trade-ins, you have to keep in mind that many of these are dealer rejects. That means the dealers didn't want to buy them for whatever reasons. If it was rejected because the dealer is full of stock, then you might be able to find a good deal. More often than not, it's got something wrong with it and the dealer doesn't want to retail it for liability reasons. So, the bottom line is: go with someone who does this for a living, i.e. a used car buyer/manager. The guy I went with could tell a good car from a lemon within a minute of looking at it and touching it. If you can't do that, or doesn't know anyone who can, stay away from the auctions.
