Poor storage space for little items like sunglasses, wallets, change, phones. Ride position is very low with the sport package. Transmission and brakes make for poor stop and go traffic comfort. Rough shifts in the mornings. Handles and drives like no other sedan above 70 mph. Horrible car for speeds below 30 mph. Large turning radius and bad blind spots. I bought this car with much regret and can't wait to get out of it. Nice looks and performance at high speeds but worthless in every day traffic. IDrive is plain horrid and after 6 software flashes it crashes randomly for 2-3 days at a time. Techs can't figure out why. Bluetooth works great, nav is the worst I have seen. Not worth price.
Power when there is not a lag on initial pedal depression, Handling at high speeds is the best, Big trunk and lots of rear seat space. HUD display is very nice. Good looks.
Update navigation display and function, revise iDrive to make it more intuitive, interior looks too industrial and cold, add more personal storage space, put some decent cup holders in this overpriced vehicle. Make iDrive stable and quit making customers flash software so much.
