i wouldnt spend under a grand for a respray, chances are corners will be cut and finish will be sh*t, you could save a bit by stripping the car down and trailering it to the bodyshop but as far as prep is concerned the general consensus is although its simple in theory many bodshops spend more time putting right the prep someone has done in the misguided notion that its a case of a bit of flatting back and throwing it at the bodyshop.
