How much can i sell my mitsubishi eclipse gs spyder

Check Edmunds or the Blue Book. It all depends on the miles and condtion. If the top does not work then you are probably looking at $2,000 or so max.

I can't tell you because you didn't leave enough information. Check and see what Blue Book says, then add 40% to it. That's always a good asking price. Or you can go to NADA, get their average retail price, then lower that by 20%.
