2007 BMW 3 Series 328xi 4dr Sedan AWD (3.0L 6cyl 6M)
I have had this car for two weeks now and absolutely love it. This car is solid, smooth, fast and of extremely high build quality. Handling is so stable and accurate. I have had two previous 3 series and this one blows them away. Its not a slow car, but its not a racer either. Put it in drive sport mode and it feels as fast as my G35 coupe I traded it in for. I do think it could use about 15 to 20 more ft/lbs of torque though. My past experience with BMWs is that they get much faster as they break in. The 2007 model has 15 more HP and ft/lbs torque than the 2006 model.
Bluetooth is amazing; it's easy and very, very clear on both ends. The stock stereo sounds really good. Sport package seats are amazingly comfortable and the adaptive xenons are extremely cool.
More torque, and lower the torque band from 2750 to 1400 RPMs. I know BMW can do this without losing efficiency.
