Great vehicle. So much fun to drive! I recommend upgrading to the sport package for the larger wheel size. Makes a big difference in the handling and the looks. The run flat tires do start to make noise after a period of time though. They can be replaced if you complain about it before the car has reached 10,000 miles.
Handling and braking performance. Also the rain sensor is nice. Oh and the door handles the illuminate at night when unlocking the doors.
Getting rid of the run flat tires and using good Michelins.
