Like every one else has said:
Two things to consider
1. Paint and the $ to do them
2. If you want a change: A. Painted you have to do a complete strip of what was on there and start over
B. Vinyl you warm up and peel off and on with the new. Vinyl will not allow the paint under it fade as will the rest of your car, so there may be a slight color difference with the paint.
ALWAYS PROS & CONS to it all.
Vinyl places: Rich one of the best, and now another place called SPEED GRAPHICS
