2002 BMW 3 Series Wagon 325i Rwd 4dr Sport Wagon (2.5L 6cyl 5M)
I just switched from an A4 to the 325i. I wish I would have made the move sooner. Even the base 3-series handles well, is smooth, quick enough, and has a comfortable interior (albeit small rear seat and trunk). I'll be looking to move up to the 330 for my next car.
Handling, exterior styling
Nothing major: maybe adding an armrest next to driver and additional power outlet would be nice.
