Nice photos - we appear to have near identical M3s.
I can tell you from experience: it's very hard to photograph the SSII color with the black GTS wheels. It's a very challenging combination - either the car shows up, and you can't see the wheels, or the spokes are visibile, and the car is overexposed.
It looks like you've done a pretty good job with it, however.
Of course, the in-person appearance of this combination is unbeatable, in my very biased opinion
