Really enjoy the car except for the minor problems. Car has great performance, could only imagine it being perfect with the new LS 460's engine. Needs a bigger fuel tank, better seat heaters, and the Mark Levinson stereo needs more bass... nothing an aftermarket JL Audio sub can't cure. Car seems to have a few rattles in the dash that dealer has yet to narrow down and the brakes began to squeal. I was told that these are performance brakes and its normal. Lexus's solution is to put on less performance pads and lose out on the great brakes, I don't think so. I also would like to shut off the way to sensitive traction control, which I believe you can on the 2007.
The navigation is pretty good and easy to use. Love the blue LED lighting in the cabin and the engine isn't bad considering it's 14 yrs old. Needs to rev more and really shove you into the seat with a good sound. Lacks the sporty bass sounds of a Northstar V8 or Mercedes V8.
More power, bigger fuel tank, better manumatic shifter (shifting is delayed, but does hold your gear which is nice), if possible even more creature comforts and better cornering. The car rides nice and firm but once you get into the corners, it rolls too much. Offer a performance tire upgrade.
