It's time to take a dive for the 325i SP then cos 28 bhp and 20 Nm of torque is quite noticeable!
Its time to cross over to the dark side....
Couple of things to look for in your test drive, coming out of an E46
1) The E90 is decidedly more refined in its tactility which can be a good or bad thing. The steering and low-speed response, though very good, is a touch more isolated than the E46.
2) The low-speed ride can be jarring especially with sport suspension and big RFTs. BUT, that doesn't mean the ride is always going to be harsh. The car soaks up medium to high-speed bumps very well, maintaining its stability/composure at all times.
3) The E90 truly shines in medium to high speed sweeping corners. Once you've dedicated a line, play around with the step to keep you in ideal rev range and just follow through. No white knuckles here.
4) The E46 will feel more cozy and intimate (some say, feels sportier)
5) You might find the E46's cockpit layout more traditional and appealing.
6) Interior material grade may appear better in the E46. But build quality is there, mind you.
7) If you hit the upper RPM's the N52 comes alive. Depending on how green the engine is or how adapted the step is, low-speed acceleration may appear dull, but this engine loosens up well over time. My engine feels much better at 10k miles than it was new.
8) You'd love the Sport seats and steering wheel!
9) I-drive has a learning curve so don't be discouraged at first. It will remain slow though.
10) The E90's side view mirror is too small, I'd make ample adjustments to avoid blind spots.
