My sister had a red R50 Mini that had terrible lacquer peel by the time it was 15 years old, and Mrs Tidy' R56 was starting to suffer from it too at a similar age.
But my Imola Red E46 had none anywhere when I sold it at 16 years of age, so maybe it varies depending on which shade of red the car is?
Red is quite an unusual choice on a BMW, but I loved mine and think Melbourne red looks fantastic too!
