Fun to drive, but...
 This is a car that could have been great, but was let down by lots of details. My car was equipped with the sport package, which is uncomfortable for around town driving and causes the wheels to pick up excessive road damage.  The run flat tires tramlined dangerously at the slightest rut in the road. This car had serious reliability and quality issues.  My car was delivered with a coolant leak.  Also, the steering wheel lock failed leaving me unable to start the car. The passenger airbag failed in the 3rd year. There was a rattle in the dash that wasn't fixed despite several trips to the dealer. The driver's side door pull is made of painted plastic and was peeling when I returned the car.
