Paint always depends on the quality you want, you can paint a whole car for $500 or spend 10k or more
It varies so much with quality of paint used, body work needing done, what you want removed it left on the car, wet sanding and cutting so many factors. Your absolute best bet is to sit down with say Kevin and the car and fully explain what you have and what you want it to be when it is done and he will be able to explain the options to meet your needs and budget.
