I'm already paying $3/gal for the nastiest, dirtiest, low-octane crap available in the UK and found only on US bases, but I guess it's better than paying $6/gal off base. Just replace the fuel filter every 10k miles and use that water remover stuff before and during winter, and it shouldn't cause permanent damage to the car.
And SUVs are still best-sellers, with the power-at-all-costs-but-not-from-my-pocket crowd griping about the new mileage standards Pres Bush got passed that requires pretty much all trucks including SUVs get better mileage in the next few years. Oh the horror.
There are a lot of people practically holding their breath until the new US diesel standard comes into effect, because the European diesel cars are just awesome. I have some Danish relatives getting 40 mpg in their turbo diesel mid-size wagon, but if it didn't have a little "TD" badge on the back, I never ever would have guessed it was a diesel. There was absolutely no hint that it wasn't any other gasoline powered car, from the smell, the sound, the performance... Nothing but the high fuel efficiency and that little TD badge. I think it'll open a lot of people's eyes when those suckers can be sold in the US. I think that when the US markets can use those engines, we'll see some 60mpg turbo diesels on the streets that give the hybrids a run for their money. They'll be cheaper, won't need new batteries every few years, but will get the same mileage with great drivability and no chassis limitations you might see with a hybrid.
