Bruh, my only vehicle for close to two years was a truck that I inherited, a 2002 Chevy Silverado 1500 LS. I believe it got about 8mpg on average, but I dealt with it because I didn’t have any other way to get a different vehicle at the time.
Nowadays I drive a 2018 Ford Fiesta SE. The difference is night and day. Stops on a dime, accelerates quickly, I can fit it anywhere I want, and it gets an average of 34mpg. I went from paying between $75 to $125 every week and a half for gas to spending about $30 over the same time period.
