Well, at least in the States, we were spoiled for ages. Europe paying 4-7 US dollars a gallon when we were paying 97 cents. So with good marketing, SUV's are (were?) the rage.
Now the chickens have come home to roost, and those who laughed at my 89 Jetta wish they had the mileage I get (Though I'd like more:) ).
Now with ULSD in the States, and what it costs to make it, I do not see diesel ever being cheap again. And I don't have to tell anyone here that even with the higher costs of diesel, it pays for itself in mileage.
But gassers can't (or won't) comprehend that. Their loss.

On a related note, I took a 2009 Jetta TDI for a test drive yesterday. BIG BIG difference than my 89 (imagine!...lol)
Gonna take a bath on my F-250 if I trade it in, so I may just keep it. And keep the 89 cuz I want to. Should be an interesting ride to Canada for the campout at Ronbeau in a few weeks with the 89.
Stay well.
