I saw the Gerz Black IRL in Garching. In the dark or shadow it`s black, wen light is shining on it, it is a kind off darkblue, a little more blue in it than Carbon Black.
I saw all collors but the red one.
1 No Gerez black for me, because the roof doesn`t come out too well.
2 No white, everyone wants wite, now everyone is too much for me.
3 No Interlagos blue, it is definatly to purple in the shadow, in sunlight however it is nice, in the Netherlands we have more clouds than sun, so this is an easy one.
4 No space gray, buy that collor on a 335i.
5 No red, have not seen this one IRL, so can not tell to buy it or not.
6 Yes Silverstone, now this is something else we are talking!
For me this is the one..........................
Roof makes perfect match with this collor, only available for M3-5-6, so it`s exclusive M, Fox red leather, 19" ....................yes ready for serious business
