Well an EV conversion would be the only way to get one of those out of its own way. There's a reason OJ's bronco chase was so slow... My ex insisted we get a mid 80's bronco, and it was so bad. I think it averaged about 6mpg and good god it was laughably anemic. If it was me, I would look for a early 70's or late 70's bronco. Totally different styles for each, but still better than the mid 80's anything.
