Incredible Handling--Run Flats Stink
 This car has fantastic handling.  It is well-balanced, and the steering reacts almost immediately.  The interior is well-designed, although iDrive is still a pain.  I have the convertible, and, if I had to do it over again, I would not buy this car.  The miniscule trunk with the top down makes it impossible to run even minor errands. I cannot even remove my tennis racket without going through the machinations of putting the top up. Even more frustrating is the harsh ride inflicted by the run-flat tires. I changed mine to regular go-flat tires one week after purchase, and the ride improved immeasurably.  Overall, a nice car, but  the trunk space and run-flats ruin the experience.
