Alright, I've found one car that might work, and another that certainly will.

eBay Motors: BMW : 8-Series (item 330145619488 end time Jul-16-07 13:33:41 PDT)
There's the car I really want, but since it's at $9,000 now and still has another week on it, I figure the car will go higher than that. It's just, I've always loved how the 8-series looked.

But I found one with a Buy-It-Now below $10,000.
eBay Motors: Porsche : 928 (item 300127250669 end time Jul-12-07 16:00:00 PDT)
That's the car I will get if people decide that the 850 won't go for under 10 grand. I have a memory as a child of seeing one of these from the back and just loving how they look. In addition, I love the uniqueness of the pop-up headlights, and the front-engined Porsche.
