Your going to have to define what you mean by a paint job . Is the car down to bare metal , is some/all of the prep work done etc etc . Somewhere between 1000. & 10,000$ based on your question .
So many variables, it's hard to give a guess how much it will cost. Is the existing paint solid enough that it can be scuffed and shot over? Do you just want the outside shot, or do you want jambs, trunk and underhood painted? What's the labor rate in your area? You'll get a better job and save some money if you remove the stainless fender beading before delivering the car to the painter. Visit some of the local shows and cruise-ins, including the hot rod and import showsl Somebody will know a painter that does side work that will give you a decent job at a savings.
I was thinking along the lines of take a night class and paint it yourself at VoTech. That is what I did
I guess it was an unfair question to answer with so many variables. A few years ago my truck needed just the hood and front bumper painted and got several quotes ranging between $1200-2500. But I ended up letting a small side road shop do it for $500, I was very sceptical since he was so much cheaper but figured it's just a work truck and it doesn't need to be perfect. Well I was shocked with the results looking excellent.
Stopped by there today and got a quote to paint it Healey blue with white trim and under hood and trunk for $1800. He said the current paint looked fine to paint over and I will remove all the chrome. I think I will just go with this since it seems like a reasonable price and know he does good work.
