Diesel cars aren't AVAILABLE in the US. I bought a new car about 2 years ago. They sell the same car in other markets with a diesel. I would have paid a premium for the diesel. Not even an option.
There are NO compact or sub-compacts sold with a diesel in the US, except for the Volkswagen Jetta (which I didn't want with any powerplant). When American's complained about getting a joke SMART car that got about half the fuel economy the Canadian diesel version got, they stopped selling the diesel versions in Canada, instead of selling the diesel in the US.
I dream about being able to buy an AWD/4WD Hatchback/Station Wagon with a diesel (like the AMC Eagle Turbo Diesel). Someday, it might be an option again. Dare to Dream.
