2009 BMW 5 Series 535i xDrive 4dr Sedan AWD (3.0L 6cyl Turbo 6M)
Just came off lease on X5 4.4 and considered X5 (4.8), Porsche Cayenne S and A6 (didn't like looks of E series but strong bias for Germans). Wanted sedan for performance and fuel mileage, didn't need exhaust note of V8 or ridicule from wife over "Porsche" name plate. Needed all wheel drive for winter. So far this is the perfect car -- handles so much better than the best handling SUVs. Very responsive - turbo lag only noticeable to extreme gearhead. Exterior is a little boring (not as much as A6) so get some nice wheels.
IDrive is much improved with feature and memory buttons, iPod control, bluetooth and voice control; 20 way comfort seats
