I wish we could get the European diesel models over here in the US. Last September during my 2 weeks trip to France I rent a Peugeot 407 Diesel. It was amazingly pepie and fast and I got an unbelievale 61 mpg (US) average. The car was also very quiet. I also got a ride iin one of my friends's X3 diesel. It was too very quiet. The noisy, smoky and winded diesel cars are things of the past over there.
