It has been easy to get parts to make radical revisions to American cars (crate engines) for a long time, much more so than other carmakers. Also, American carmakers have long been obsessed with trucks to the point where sometimes I wonder: Will they stop making trucks? Will the people who used to think cars were a problem for the environment (with bicycles, busses, walking being answered) come to see trucks and suvs as the problem and cars the solution?
