Don't think I could guess on a price on the car - haven't kept up with Camaro's lately. As for painting it, that would probably draw more potential buyers. Pretty things draw attention. However, I would prefer to buy the Camaro still needeing paint than with a cheapie paint job. The primer condition would allow me to have the work completed in a quality fashion. Guess which way to go depends on the buyer.
Most collision shops do just that, bang out the insurance jobs. Don't know about your area but around here there are a number of individuals who work on the side. Ask around for a contact or reference.
That is a very nice looking Camaro and can tell you've put a lot of work and money into it. Too bad you won't be finishing and enjoying it for awhile.
