I had a 1962 Buick Invicta that did the same gas mileage, here in England in the early '80s. I own a 1946 Ford pickup now, 15 miles to the gallon.When I see dates like that it makes me feel old, my hub is almost 13 years older than me, in ‘69 (the Summer of Love, the Moon Landing), my hub was 21, still with his first wife, owned his own home and (to this day), his prize possession, a brand new Olds 442,,,of all his cars (over 70), that he owned, that’s the one that stands out,,,at 4 mpg he couldn’t afford to own it today, LOL
