While I completely agree that the colour of any car can make or break it (saw a vw up in black for the first time and thought that's quite tidy! ), there's too many variables to consider when looking at used car prices. Age, spec, mileage, condition, service history etc etc it's too hard to find identical cars to compare the prices on colour
Yes azure, chilli, night blue might be more attractive to most buyers and the right colour cam transform the appearance of any car, it's a very personal thing. Im not a fan of sunset zeds but some won't consider any other colour
Anyhoo I'm booking my skyline in for a brown respray with a pink roof
