you know what else...... when they complain about the price of gas I say how much is it? and how far does ur SUV go on a tank? then they ask well don't you know.... you buy gas too. right?
ME... nope not bought gas in a few years.
them.... Is your Jeep ELECTRIC then?

as if they never heard of diesel.
then you explain it and the 20-30% better fuel economy with diesel and the slight price difference..... you can see them try to grasp it as the gears in their little heads turn then they say but it costs more per gallon it can't be cheaper. Just like warp says they don't get it
