It all depends on the quality you are looking for because that is subjective. Knowing your quality expectations prior to starting are key to costs.
This is with a bare body stripped of all trim and glass.
Sure, there are people who can do things for a lot less and have their special ways of keeping down prices for budget purposes single stage vs base/clear it still has to please the client and the painters abilities should accommodate their needs. Some clients are insistent and fastidious and desire higher levels of quality and there are (hard to find) talented painters to work with you to provide that level.
In the refinish industry many man hours are generated into the degree of preparation you require for your plan for the car. Media blasting, body reconstruction, frame machine, X checking, sheet metal fab, flattening existing sheet metal outer panels. and leveling all panels prime and lots of blocking prior to color. Blocking color coat can take considerable time depending on your vision of quality.
If you have high expectations expect 35-45K+, medium expectations 15- 25K, standard work 10-15K . Then there is just get it done 4-10K +.
Maaco etc have their packages maybe 1-2K unsure?
Industry man hour rates average 85.00 to 150.00+ per hour (estimated) usually based on time and materials. expect around 300+/- hours on just the refinishing.
On these cars expect to see additional hours for unexpected rust repair and reconstruction from previous "repairs" of sheet metal.
Expect to purchase sheet metal parts.
Some like to keep it simple I definitely get it.
Its not for everyone that`s for sure.
Good luck on your quest fellow 02er!
