My last car was painted by Maaco. It had the $250 paint job that the PO thought would be okay. Unless you do the paint prep yourself, it's not worth it. They're literally going to shoot paint onto your car. My 2 year old paint was peeling the day I bought the car, and was coming off in sheets the day I sold it.
I really think it's a better idea to prep the whole car before bringing it in, as they won't do it for $250.
