Here is how I look at this. True zero feedback is risky, but it may be to someones advantage. Call this person up, you might find that they are a dealership and have a good reputation, point out to them all of the faults you guys are noting and then submit an offer. You never know, they may actually take $4,000 for it. Chasin, I think its great that you got 3 cars for $3,400, but if you had a rare car like an 87 300TD how would you list it on Ebay?
I thought I remember their name from somewhere, check out the other cars that haven't been sold, one is an older wagon:
