I think paint and body prices vary quite a bit around the country....but when I painted my car (convertible) 6 yrs ago, my friend who used to restore cars gave me a good tip...to avoid the pointer (unless you use Maaco or such) to think he is going to have to have a classic car owner being almost unrealistic in perfection, you`ll do a 'repair job'.... my car needed some rust repair (patch panels on rear qtrs) , it got a new used blue hood (different color than car was) , car already had a red fender in a different red color than the rest of the car...but the car was in a fair shape re trunk lid , door jambs etc...so I had the car done in two trips, not ding jambs or inside of trunk, but got a "matching" paint as to what was on the car...
my hood, front nose, fenders valance, cowl with some metal work under to the inner fenders (rust holes), was $1240....then I drove it foe 5,6 weeks took it back, 'repaired' the doors, rear body plus the patches, it came to another $1280 or so...matches fine...its a 'fair' paint job ,not a show job...but looks good....
then a friend of mine had a $1000 Maaco job, two tone , that also looks great...thats going to be depending on the shop, this shop had a forman that was very interested in doing this job...some are not...

some overspray is not a big deal, on chrome or rubber you can remove it, on underside ,inside fenders etc you can 'cover' it with black paint....
not sure I answewred your question ,but hopefully you`ll get more and can by several answers get a good idea
