I have owned this car for 11 months and put on 14200 miles on it. I have driven all four seasons now and can say that this is the best SUV I have driven. Performance is Awesome.

My friends say that they could see a big difference in my driving style. If you drive it slow you get the best possible mileage (31 mpg). I drove 270 miles non stop and I looked fresh as I started to drive. Get the Premium Audio and it is one of the best&Every Penny is worth it.

Tailgate closing by remote is not an option in US but it is standard in Europe.
Price is the other factor I would suggest an improvement.
