Gas mileage. Oh boy. I get the biggest kick out of people that state proudly that, "I went to (wherever) and back on a half tank". Whoopee! How big is the tank? How accurate is the gauge? I know that I can go a lot further on the first half tank in my old Sub than on the second half.
I always remember my boss telling me that when he was buying a nice new Chev Tahoe in about 2001, he asked the salesman what mileage he would get. The salesman good-naturedly said if he was worried about mileage, then he probably couldn't afford the truck! So true!
