Runflat tires ride harsh noisy and blowout. Had 750i with 20 inch tires the ride and handling much better. Steering feel is more like Lexus then BMW. Rear suspension hits bumps very harsh. Not what I expected from BMW. Rattles inside over bumps.
Engine, transmission, looks, dash layout, seats, I-drive and brakes.
Cup holders, steering, rear suspension, better interior quality, tires, and better looking wheels
