Colour's are personal preference and for me very dependent on the car, Clubsport S I'd only have a white one, TCR I'd take the grey all day long, standard GTI / GTD I like the red, I hate green but I wouldn't want any other colour on my Mini
, think no matter what colour it is you'll find an issue, black is terrible for swirls and scratches, white is constantly covered in tar, red eventually fades and the list goes on.
I'd never let the maintaining of a colour put me off, way I look at it is if I buy a different colour for that reason I'll only regret it every time I see one in the colour I prefer, I say buy it and then worry about the consequences, silver is much easier nowadays to get an exact match and most decent body shops have the tech to do it properly.
White silver is an odd one, don't hate it, don't really like it but standard colours always seem to age better than some of the more unique ones IMO, much easier to sell too, but each to their own
My car and van are identical in that flat white so I'm just a very uninspiring person willni
