E46 had a dead zone in the steering, E90 no dead zone, feels good, real good.
In terms of pushing it - E46 and E90's behave much the same. Take a bend with no throttle = understeer on the limit, same bend with throttle = oversteer on the limit. DSC on the E90 allows for 15 degrees of drift before cutting in (according to the salesman (which probably means it's utter horse poo

)).
Brakes on the E46 were pretty good, rarely had any fade, no fade experienced on the E90 yet but I've only had it two months.
Suspension feels the same, both cars well sprung, minimal body roll.
Not really relevant but it seems with the new age 3 series things have moved up a notch with performance; E90 325d performs same as the old E46 330d and so on.
I like the gearchange on the E90 a bit better - feels precise but it's very notchy though so if effortless gear changes are your thing - avoid!
Stiff clutch is starting to affect my left leg muscles - I've started walking around in circles.
