Jason - I'm kinda done with the Lexus - had a major problem with the dealer and Lexus NA - the front brake pads and rotors needed replacement at 14.5k miles - I could maybe understand the pads being replaced but not the rotors - and they will not replace under warranty - so I paid out $900 -and it's not the money thats so much of an issue, but the principle
so bye-bye Lexus forever
and Lexus NA would not do anything about it either - kinda disappointing since they thrive on thier supposedly superior service - been to a few Lexus message boards and numerous complaints about the front pads/rotor issue - probably a class action lawsuit would wake them up...
Back to the replacement - test drove the '07 X5 4.8 - absolutely hot vehicle - I owned an '02 4.4 - and the new one is a 100% improvement...so the X5 is definitely on my short list. Also, the 335i - 6-speed, although didn't feel as fast as an E46 M3, it certainly would keep up with it...
