the 1M is an amazing car on the track. captures the essence of the E30 and E36 M3, which the M3 has irrevocably lost. but with much more power than those two.
if i wanted a modern E30 M3, i would pick the 1M over any other BMW offering without hesitation. but i needed the best GT/high performance vs practicality compromise, and for that no other car from any marque is better than the E90 M3.
