Four pots are rough IMO, even in something new and German, Six's are a different ballgame, the difference in refinement from a 4 is astonishing, much more so than moving from a petrol 4 to a petrol 6.
I owned a 335d for a while to do some development work on and it made pretty much the same numbers as above. I was a little disappointed to be honest. It was a fast car but I think I expected too much. Probably due to tuned diesel owners constantly banging on about how fast they are!
Turbo petrol six's are where it's at for me, power, torque and refinement - they are just a little out of reach for most.

i gotta agree the best thing about tuning is loads of revs and power which isnt possible with a diesel.
as a daily car though that 635d must be lovely, smooth economical lazy grunt, but i need that 100s of hp uptop aswell as loads of low/mid range torque
how economical are these 635d mpg ?
my 3.8 gtr will return from 13mpg city to 26 mpg motorway roughly
