What do you think helped the most in MPG/ the 5.9 engine (lower RPM) or the A500 overdrive ? When your on a fixed income fuel mileage is important. A vehicle that sucks fuel like a pig..does not get driven much.
People say "smiles per gallon" but I guess they have more money to buy more fuel, someday they may not be able to spend as much on fuel...then they may change their minds/or not.
