I'm sure they are paid well not to understand. My daily driver is a Duramax Crew Cab 4WD, I do love diesel power!  I've also have a 1926  4da0   Model T Open Car Pickup restored and stashed away if I ever need it. Also a 1972 Chevrolet SS 454 repowered with a ZZ502,  not sure how the Chevelle would hold up to EMP; electronic ignition and programmable electric fans are susceptible. My Model T truck looks pretty much like this - http://www.2040-cars.com/Ford/Model-T/1926-ford-model-t-runabout-pickup-1165812/ and I've read gets about 20MPG. I have yet to drive it out of the yard.
