I test drove the 2008 BMW 535xi & 528xi, Audi A6 3.2 before buying the 2007 GS 350. A real comfortable ride but a little harsh sometimes w/18" wheels. Hit a pothole and tire had a bubble, Lexus replaced for free!
Bluetooth, navi, ML audio, 18 inch G-Spider wheels.
An iPod adapter, smoother ride with 18" wheels, 4 year free maintenance.
