Hi Hi!
As mentioned pistonheads and amoc are the only ones I've found so far, they are not very active though.
AMOC seems to be great for answering questions, and the general lack of too many topics may indicate that there aren't too many problems with the car.
No need to 'mod' a car so beautiful, so the lack of those discussions is forgiven
Waiting for my coupe, manual, black/black silver stiching with all the goodies.
It's intended to replace my M3 as a daily driver/long distance GT, should end up being simply a more beautiful version of the same purpose car
