How about simply requiring posts of cars for Sale, include a price and location and possibly one pic would be nice as well. This I think it would save several thousand post of "price and pics to such and such e-mail addy"

The rest of them can be thrown into:
The "thinking about selling a car at a price I wont tell you at a location I wont tell you with a condition you cant see until you post an e-mail" thread.
