Traded in 2001 BMW M3 for TDI Sportwagen. So far with 4,900km (3,050 miles), most put on in one 3,400km road trip, I am very happy with both power and mileage. Climbing a mountain pass doing 75mph with cruise control on, the transmission never shifted out of 6th gear. This is with the car totally loaded down with luggage and 4 passengers. Only minor complaints with "buzzing" in drivers door on certain road surfaces and a creaking on the passenger side of the sunroof. I will take these to be fixed when I take the car in for it's 1st service.
TDI engine torque, interior fit and finish, cargo room, leather interior (yes it does exist in Canada)
Turbo lag (DSG), fully electric seats, Nav System (Not available as an option in Canada), Automatic Climate control on TDI, better carpet (it is pretty thin and the Beige color is a dirt magnet). Auto dimming mirror, 115v outlet in console, homelink.
