The dealer won't be able to turn over that car right now, and might end up sitting on it and risking some serious cash. They can't give you a dime over wholesale unless you're trading in and paying a big sum for some new car that they're making a ton on.
I don't like dealers that much, but I know about business, and they are in it to make moolah. If you want the easy route of trading, you're going to get less for your car, that's just the way it is.
A 2001 Vette can be a tough sell, but it can be an easy sell when the right guy comes along. Make sense? If you want top dollar, sell it yourself.
Sure is a killer selling it with only 10K on the odo, though. That car was about $65K (at least) right? Suppose you get $45K for it, you took a $20,000 depreciation hit. That's $2.00 a kilometer! Not inlcuding gas, insurance, etc. I hope every one of those 10,000km's was pure bliss...
