Myth number five: "You NEED something newer to get be more reliable and get better gas mileage."
I can't tell you how many times I've heard that from the relatives making fun of my not-so-old (1973) Chevy truck! My Ol' Blue isn't "pretty"; it's a working farm truck that has outlasted and can outwork any of their vehicles. I get the exact same mileage as my uncle Roger does with his fancy com-puke-erized, fool-infested Dog truck.
