I test-drove X6M few days ago. Awesome car/SUV. Mrs first comment: So big, taller than her. Anyway, after that off we go with 3 adult and my 2 kids. In term of comfort better than my e92 M3 but my M3 is on 20" wheel. Can still feel the X6M suspension/tyre a bit hard but better, it was on 20" as well. As I pass DUKE highway toll plaza I press the M button, change to MDM mode. Shift down to 2nd gear and floored the accelerator. Feels slight delay in the pick-up, compared to my M3 with manual g/box. Anyway in no time touch about 120+ on the head-up display. Then I realised it was actually mph not km/h. At that mph I shoud be about 200 km/h already. The car/SUV is so stable I don't realise that I was driving at >200 km/h. Mrs didn't realise the speed till I informed her, she said the car still feels slow. Now, if I can get a good price/buyer for my M3...
