maaco does really cheap paint jobs, under $500 and it can belooking good..... for a year or two before the cheap paint job shows why it was cheap.
paint is paint is paint. it costs basically the same no matter who sprays it. prep work is where the price really changes, and you cant have a long lasting quality paint job without serious prep.
the beauty of prep work is that it doesnt take much skill for most of it. remove the bumpers and everything on the body that doesnt get painted, light sanding the entire body, taping up windows, those dont take much skill, but they can take LOTS of time.
do them yourself and you dont pay for them to be done.
