Geoff,
We have friends who have a 2007 Jeep Cherokee diesel and LOVE it! If they keep their speeds under 65 on the hwy, the jeep is getting 25mpg. 20-21 around town.
Unfortunately, we, as Americans, are unable to buy a diesel Smart Car. They are available in Canada, but we can't import them. It just so happens, I talked with our Smart Car dealer yesterday and asked about diesel power.
They said no diesel , but there maybe a electric version coming. Bummer, I would by a diesel Smart yesterday if I was able.
