Hi,
Why dont you find a dealer who can let you accompany him into the Manheim Auction (Riverside ,CA). You can then inspect the car prior to bidding and decide beforehand on how high you would like to bid. You can also make a deal with your dealer on how much you would pay him over the cost of the car ($100 ~ $500).
This way you would be more in control. I can try and get you the name of a dealer in the LA area who may be able to facilitate that.
Goodluck
