FWIW I've averaged about 18 total. Best was 24mpg over a low speed highway (55-60mph in 7th gear), worst is ~6mpg on track.
But having owned a 335i, the driving experience is not even similar. The M3 just feels like a much more expensive and more solid car. The only thing the 335i is better on is low end torque and mpg's.
Owned both, disagree. As others attest, 335 slightly modded = rocket.
Both nice cars though.
Hoping the new M3 solves the current cars ills.
