I just traded an S55 AMG in for this Lexus. There are many pros and cons to this car but it could definitely use more horsepower, more high speed capabilities, and features geared to the driver and front passenger rather than just to the rear passengers. Really how many of us have a chauffeur. I do enjoy driving the car but admit I was a bit spoiled by my German auto performance and it's being geared to make driving fun for the driver.
Comfortable seats, controls are easily accessible.
It needs more voice commands, the navigation system needs more available features when the vehicle is in motion such as the Acura TL. Stereo needs 5.1 digital sound and needs a much better subwoofer. My 2001 Mercedes had a better factory stereo. Car is subject to road wandering at high speed.
