They're exclusive that's for sure.. But all you're getting over a 135 is wider wheels, wider fenders, 40kg more weight, 0.3 seconds faster to 60. I think it's got stiffer suspension too (which can easily be changed on the 135).
The only real selling point for me for the 1M is the fact it's got an M3 LSD. Oh and orange. Orange is cool
You're also picking up a car that's appreciated in value since launch rather than depreciating.
