I posted quite a while ago that when I drove the 335i with a manual I was totally underwhelmed and thought I'd left the handbrake on!
Lacks torque, the power delivery is too artificially linear for a blown engine, or at least for my tastes and it didn't sound particularly exciting either.
The 30D, on the other hand, "feels
" much quicker at any speed in any gear and even sounds better - it has a much more gruff and purposeful engine note to it
DaveyC - I know you think you'll miss the sound of the gorgeous BMW 6-pot but you'd miss it on the 335i now anyway because it's blown and not NA. The character's all gone
Have a gander at YouTube for F30 335i and 330D vids and listen to the sounds yourself.
Oh, and don't bother listening to all the exhaust note vids because it's a trick sports exhaust and it doesn't sound like that in the car
