Not much George ......no chrome comes off, bumpers stay on. jambs would be extra ect.... plus like you said with the prep workMaco has been advertising a half price special for $275.Anyone know what you get for that? I guess they make money on the prep work.Some Community Colleges offer courses in auto repair. It might work out if you can find one to sign up and do your prep work along with advice, or just talk to Maco and and see wht you can work out. That's assuming Maco is everwhere.
