Yeah I agree with low about $6K to $8K, more with stripes of course, and yes prep has a lot to do with it, also the time of season...
I burned through $4,200.00 just having some body molding work,side sills,wing,hood roof vent, and touch up stuff done..
I had a bunch of scratches also, body guy just sanded and recleared, no need for repaint, also they have a product called "REJECTS" it removes most scratches and leaves a polished look that spanks, had mine done last week...
