Here's a giant roll of the dice

Hmm....$5500 for a 2001 S, could be the deal of the year. Supposedly a repo so you you have to assume that it was being driven. At the worst it is not a bad price even for a roller.

Dealer auction + dodgy seller = potential legal issues.Bin there done that. Make sure you get ALL the documents. The guy's d.license info, a signed "statement of facts" future address.
It could be stolen/liens etc.
Go to an agent for the local DMV to investigate the history. If it is a suspicious vehicle and you go to DMV ,they will nail YOU right there!
Assume the worst(roller/parts car ) and price accordingly.
It could be legit ....but then again.....
