I've gone to the Newburgh, NY Manheim auction twice and actually bought one car there - my 2001 Ford Explorer. I know they have auction houses all over.
It basically works like this.. ask the dealer you are going with for his information on what they are putting up for auction on the day you are going. You can either get a booklet at the auction house, or perferrably go online to look at what they are putting up. You need his log in info in order to look online on manheim's site (if he is set up to do that - not sure on that).
What I did was pick about 10 explorers to look at from the huge list of vehicles online, and printed out the info for each. Then, I paid for carfax and ran each through it and if anything came up on any of them, I crossed them off. Then, on the day of the auction, we got there early before the start of the auction and looked over each. Each car has a number, and you have to go out into the mammoth parking lot and find the car and look at it. The keys are in each car, and you can start it up, drive it around the parking lot if you really want (the attendants get pissed because you mess up their order) and look under the hood, etc. After the initial look through, I had narrowed it down to 4 cars from about 8.
Then, you look at where the car is in the order of cars to be auctioned, and find the lane where it will come through. Newburgh has like 10 or 12 lanes of cars running the whole time. Then when the car comes up, only the registered dealer (with a dealer sticker that he gets for the day) can bid on the car. So you have to be standing right next to him and paying REALLY close attention to the auctioneer. They talk really fast, and often you lose track of where the price is at, since its not like they put it up on a board or anything. You dont want to be bidding against 3 or more people for a car, because that will drive the price up.
Then, once you manage to buy a car, they DO have an inspection place onsite, and that costs $100. They go through the whole vehicle, and will report any problems that they find. That takes a while if you buy a car in the middle of the day, since many cars bought in the morning are getting inspected. Another thing is.. as far as payment, I believe that only the dealer can pay for the car, and as far as driving it home, it needs to have his dealer plate on the car.
Last thing is.. I dont know what kind of car you are intending to buy, but from my experience, EVERY car there has some kind of problems. It would not be there unless it did. My explorer had to have the window motor replaced, cd/radio fixed, and the tires needed replacing. I will say that it's a good place to save some money if you can deal with some problems. Be sure to inspect the car closely before you drive away in it. I think that anyone that is a registered dealer can sell a car there, so pay attention to who is actually selling the car you are interested in.
Good Luck if you go.. its an experience
