This is a great car! The only downside is that it's no BMW. I traded a BMW in for this knowing that the ride would be a lot more "soupy" than that of the tightness of a BMW and I am a little disappointed I was right. The car itself though is all LEXUS and is a fastastic car from a reliability and creature comfort standpoint. When I am not driving fast and weaving in and out of traffic I am glad I bought it. If Lexus wants to truly go after the 3 Series consumer they will have to find a way to make the car "harder" with regard to responsiveness and road affect.
Bluetooth phone and keyless entry/start.
Tighten the steering dramatically. Keep everthing else the same.
