I'm with you on loving the chrome especially on dark colours. Each to their own!
It depends how far you want to go and how much you want to spend.
Genuine mini chrome front grille and/ or surround look nice as do the jcw
side scuttles. On the mirror covers try to get the genuine ones as the stick on aftermarket ones just don't sit right to me.
Once you get into aftermarket there's tons of stuff so it all depends where you're taking it.
Plenty of fab chrome alloys out there but that takes it out of pocket money prices especially once you up the rim size and need new tyres...
I think with chrome you have to know where to stop - I'm sure we've all seen Chrysler PT cruisers blinged to death. I didn't want my mini to end up looking like that!
