Could you guys give me an est. value on a car? It's a 2800cs. The car is almost perfect, the color is graphite, and it only has 27K miles on a "new" engine. The car has been worken on by Gephardt (as in the racing guy) and there only VERY minor cosmetic things. The engine is supposed to be more powerful than the orginal. It's a five speed. Can you help me? I'm thinking about this one. The asking price is 5500. Is this reasonable? Is it worth more? Please help!
