I traded my 06 BMW 530i for the TL Type-S. My BMW had less horsepower and less torque and cost 15k more money. Honestly, I have more fun driving the TL Type-S.
Manuel transmission, The instant power the car has. You don't have to floor it to feel the power this car has. I like the navigation system with the rear view camera, and the ELS surround sound radio system. I cannot forget the red gauges.
Maybe having a rear wheel drive, or all wheel drive.
