Just completed my first commute in my new '07 X3 - it turned the twisty mountain roads into a flat, straight freeway! The V6 is very quick & smooth, handling is fantastic and up/down shifts by the 6 speed auto trans were imperceptible. The brakes are almost too good, as I am learning to be very gentle with the brake pedal to avoid stopping too fast. Looked at CX-7, RDX, RAV4, CR-V & Edge - the X3 was far and away the most fun to drive while getting better mpg than CX-7, RDX & Edge and only 2 highway mpg less than Rav4 & CR-V AWD. Storage room with back seats up or down was equal or larger than these other CUV options.
Handling, acceleration, fun to drive, reasonable mpg, awesome brakes, hands free Bluetooth phone, NAV/sound system, solid build quality, the extra large sun roof, adaptive headlights, park distance control, 4 years free service - and absolutely check out the "Comfort Seats" option for long trips!
Better cup holders - passenger gets flimsy fold out thing in dash. Option to add a hitch for bike racks without cutting a hole in rear bumper, accessory power & AUX IN hidden in console, sliding/reclining rear seats, rear view cam, voice control & traffic updates/rerouting in NAV, free floor mats.
