Respray costs are like how long is a piece of string. I’ve had two cars repainted (top coat) over the years, the cost was £1000-1200 including sorting out minor dings, but not welding.
On that car, you can see the sprayer had done some dressing on the rear panel. Turned out it was old damage from Japan, and eventually needed welding.When I brought that car, it had hail damage, every panel.
The other car repainted was my S-Special 2, which was repainted in 2009, with the GHO nose. Crashed in 2011, destroying the GHO nose. Insurance repair, with new wings and bumper, which now don’t quite match the bonnet. 2017 had a lot of welding done, and most of the rear end painted (wings, bumper, and lower door halves). In 2020, the paint is getting tired looking close up, and things weren’t helped by the garage door dropping on it.
