 Great car. Comfortable smooth, sports car handling, excellent craftsmanship incredible power. Not as quiet as the gas engine but very quiet for a diesel. You have to listen to hear it. I average 25mpg, as much as 38 mpg on the road. However the GPS stinks. It's the worst. Difficult to use and I dont need to find "border crossings" in the USA. Just buy a Garmin, a 100 times better. Problems: transmission tends to clunk into lower gear as you slow down. Had a 2005 Benz with the same problem.  Price of diesel a negative. Hate the center console, holds nothing. Service very expense. I would however, buy this car again.
