My guess was a ‘little’ bit low then
(goes to show that guessing isn’t the best idea
)
I think ‘how long’s a piece of string’ sums it up nicely. IMHO the car’s owner also needs to balance the cost of a respray against the age and of the car and how much longer they intend keeping it. If it’s an early mk7 GTI then IMHO spending £6k on a respray doesn’t make good financial sense, and it might be better putting that £6k towards a newer car.
I was viewing a £3-4k full respray today on an Evo, the painter has given money back to not have to deal with the imperfections, including lots of heavy sanding marks, cracks in the paint, paint burn through etc. The owner is very unhappy with the finish to say the least.
I think many of our ideas of 'a rough quote', are still from the 2010's, as back then you'd get a good / great respray for £3-4k.
I totally agree with you, a full respray only makes sense if you're planning on keeping a car for life in my opinion. If the cars in such a state of needing a respray at this age I'd question the care of it and if bought recently ask the purchaser if they've been to Specsavers recently.
