Just returned from a 2500 miles trip to Florida and back, and have no serious complaints. My son is 6'4", did half the driving, and never lacked headroom. The car is quiet most of the time, except on rough concrete roads. The power level is fine, storage capacity is fine, handling and braking are excellent. Have also driven it on some snow covered roads and it felt very secure. I love the XM satellite radio. The leather still feels plasticky, but it is breaking in. My only "real" complaint is that the fan cycles on and off frequently when the car is idling, and that it is very noticeable and even sets off a vibration that is felt through the steering wheel. Current mileage is around 4500.
Seat heaters work excellent, as does the climate control system. The seats heat up quickly and the car produces heat quicker than any other car I have ever owned. Also, the defogger, defroster, and heated mirrors all work quickly and work very well. I love the XM satellite radio.
