I'm sure you know this but you have to have the body preped as if you were going to paint it before the wrap...so there's little to no money savings on body work.
I'm on the fence if I would wrap a car or not. I think if I was to do one I would take many pics of the car before and during the wrap to help show a potential buyer that I wasn't hiding anything, but just chose a differant finish over paint.
There is a time and place for everything.....
