Totaly agree with that, 1.8T is not an inspiring engine. Turbo is too small and runs out of puff higher up the rev range.
M cars can be stupid expensive to run, and in the real world on roads will be no faster than a 335d
I must admit to liking the noise a 911 GT3 makes I did actualy think about buying a E 55AMG but decided though it was fast was not special enough for what would be a weekend car. At the end of the day its just a very fast saloon all be it one that sounds fantastic
Still thinking about maybe getting an Z4M coupe for a weekend car, Even though I know the 3L would be just as good in 95% of situation I would still go for the M
Do you ever wish the 335d had an LSD ? I have driven a few powerful BMW's including some M cars and I am sure they leave it off the list on purpose as they would challenge the M cars more if they could get power down better.

Remember listening to an R32 with a sports exhaust pulling away from a toll booth in France sounded great
