After body and paint you could be looking at 15k or more.I would say 80 hours in metal work and another 100 hours in priming, sanding,
and painting and polishing.To do it right it takes a lot of time.Supplies and paint will cost you 1500 dollars.What will the car be worth when done?The reason these car are restored is because 75 percent of owners do 90 percent of the work themselves.I had 60k in my car.I did 90 percent of the work with the help of some good friends.I would talk to someone on this forum who knows your car inside and out to get a good idea at what you are looking at.
