If you are still not convinced, ask yourself a simple question......how come there are so many body shops? and how can so many body shops operate next to each other? that's because they are paid by insurance companies with retail estimates. I did a 2010 gmc commercial van in 2011 with 6k miles on it. the insurance estimate was $16,100. it had damage on the roof and side, and needed airbags. I fixed the roof, replaced the necessary parts and put in used airbags, it cost me, with labor, $3100 to fix it. so if anyone out there is sitting around thinking about their future, and they love cars, get a license and open a body shop. I am now retired and do this for fun.
