When determining an overall auto painting cost, you have to keep in mind exactly what and how you want the car to be painted. The cheapest overall paint job is going to be one where you don’t change the color of the car at all. With a minimal amount of preparation, you can expect to pay in the vicinity of $600 for a single color with clear coat. This is presuming that there are no underlying problems with the current paint requiring attention, before paint can be applied. If you plan on changing the color of the car and want door jambs and such to match, you’re looking at a minimum of $2,000 to $4,000.
