After riding in one (co-worker just took delivery last week) I have to say I'm impressed. If you didn't know anything about the car before hand you might not be able to tell it from a small 6-cylinder. Honestly feels just as powerful as my sister's 325ci. Granted its a bit heavy, but I'd say its due to all the luxo-features they've crammed in the car. 0-60 in ~7.0 should be doable with the 6spd.
