We had our '74 painted two years ago and checked out several local shops. We got prices all over the place! What we ended up doing is talking to several couples in our Corvette club who had exceptional paint jobs on their Corvettes. They had all used the same shop so, needless to say, that's where we went!! The car spent the winter there...we took it in December 15, picked it up May 30. They weren't the cheapest, but their procedure, work reputation, and end results were well worth the $5,000 we paid.
We had the car repainted the same color, Corvette Orange, had just a few minor cracks repaired, replaced the front and rear bumpers, and we provided all the replacement emblems, door handles, etc. The paint job was the best we've ever seen!!! Absolutely no drips, overspray, orange peeling anywhere!!
I suggest you ask around and ask the shops if they've painted Corvettes before. If they have, ask for names and phone numbers....then call the people and, better yet, ask if you can see their cars.
You can pay almost anything you want for a paint job. What makes the difference is the quality. Quality is what we wanted and quality is what we got.
Good luck!
