"Combine that with the typically greater price on diesel vs. regular gas, and it starts to make less and less sense to buy a U.S. spec diesel."

Diesel costs less to produce and was always cheaper than gasoline, until BigOil realized it had the truckers by the throat. Outright theft, and nothing else but.

When the gas hits $5.50 or more per gallon, I wonder how often the performance cars will get out of the garage?
