2008 BMW 5 Series 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
Test drove A6, GS 350, E550 and there is no comparision with this car. Had it a week and drove from SF to Santa Barbara and wanted to continue driving, it is so comfortable and fun to drive. Sport, premium, Logic 7, Sirius, Sport Shifters.
The iPod, Bluetooth, seats, Logic 7, performance and yes, iDrive which takes an hour to master.
Get rid of cheap plastics in interior (turn signal handle, visors. etc), other than that this car is a grand slam.
