Wow...that sounds like a ride that I wouldn't want to take. We had a couple of Jeep pickups around that era that caught fire, but they were always going slow enough that it wasn't hazardous to the occupants. Apparently AMC liked to run wires through doors and through other panels without grommets. Or fuses.
The Lincoln I had was a Town Car, a little longer than the mk's, same 460 engine. Took forever to accelerate but the top speed was seemingly only limited by your courage. I never went above about 110 indicated, because the front end got a little squirrely, and it would start to understeer.
Back to the original topic, I really didn't pay much attention to all of it when it happened. But reading a few things on here make me more inclined to believe he did it than when I started. Primarily the combination of two particular things. First, that someone that knew him well was certain that he couldn't have done it. Second, that general public opinion seems to be that he wasn't a good guy at all.
Those two things, to me, don't line up with a normal person. We all know people that are sneaky, or kind of jerks, or whatever. But the thing is, everybody knows that about them. When someone is just a miserable person, even there mom is going to admit that they're a bit of a troubled child, or whatever. It's a different process, but I've interviewed quite a few people over the years. Most people are pretty easy to read, and are what I'd call genuine about who they are. Some people have a bit of a skill in presenting themselves as nicer or kinder than they really are...and some interviewers are good at spotting them. I know some people that are great at spotting these folks. I think I'm pretty good at it, but I work with people that are better. Anyway, my long winded point is that every once in a while, maybe 1 out of 100, there's someone that can fool everyone. I don't know if they've fooled themselves, or if they're excellent actors, but they can effectively be someone they're not for an extended period of time. My belief, which isn't worth really anything on this, is that this Peterson guy is one of those. He has people trying to help him out because he's convinced them he's a normal person...and he's not.
