I had a 50cc motorcycle to get around on then, it held 1 gal. Gas was 29.9¢ and I filled the tank for a quarter and drove around all week.
I drove my VW 50+ miles to work one way. Never thought anything of it. I was earning about $400/month at the time. Lived at home. I traded it in on a VW convertible, but then went off to the Army & my mom drove that until I retuned home. I then traded that VW and bought a new AMC Javelin.
