Of those three, the last of them I still see on the road is an occasional Pinto..........
So there are some that have not succumbed to rear-ender fires after all.
Wasn’t the problem one of a filler neck behind the license plate, as in the older style of American car? Except there was no beef to a Pinto, so a rear end strike would breach the neck and generate sparks. The Vega and Gremlin had side filler necks I believe (I know the Vega did).
A few years ago I saw a Vega or two on eBay, which had had a V-8 installed in it and was living in a low-rust area.
