I'm really glad you love your car. Perhaps they have improved since the early 2012 F30 328i's I drove. They were nimble and quick, but the sound and steering left me uninspired. I just kept thinking, "I can't believe this is a $40k car." Just my opinion. I really hope they have improved since the ones I drove.
Current: Sorry to see the M3 gone, but engine issues sent me over the edge. My 'fun' car is now a Porsche 987.
Prior: e92 M3 DCT ZCP, f10, e93, e46
