I love the 335is over the M3... I am so waiting to see what the next M3/M4 is going to be like tq wise... the lack of low end torque really kills it for me on the M3... yes over 80 mph, the M3 is nice, but the is so comfortable and I have had no issues with it all... already burned through a set of back tires... the is - is just so much more tossable and the exhaust note is sweet... the car is starting to finally break in and be prepared my mph went from 23 down to 18-19 now. The is could benefit from better brakes and I tried to fit race compound 35 series tires on the back w/ the 19" rims - will not fit. The is is my favorite car I have ever had so far.
I do wish I could have gotten it in carbon black or azurite black or monaco blue though
