It is still in one piece but, I want to sell the parts instead of the whole car, I am told I can make more money this way. If anyone knows anything about how much certain parts should cost it would help me out a lot seeing as I am not a car-buff.
Any information on any part will help and if...
GIMP would be the main one. If you're on a PC, one that hasn't been mentioned but is pretty powerful and very easy to use (the menu system is more familiar than GIMP) is Paint.net.
