1st: There ARE some vehicles more prone to bursting into flame. Anyone remember the name, PINTO?
2nd, BECAUSE of the lawsuit arising from that incident, I haven't heard of any widespread issues with that particular type of problem SINCE.
3rd, anyone with a gas tank skid shouldn't have a problem.
Having said that, I HAVE had a Jeep catch on fire, before. I used to own a Postal Jeep, about 8 years ago, and took it camping Near Mackinaw City, MI. It was the last week in October, and there were only a few people left in the park. I spent 5 days, and it turned from rain to snow, the last night. about 7 a.m., one of my tent stakes pulled out, so I scrambled out in the rain/snow, and put the stake back in. About a half hour later, the other side hit me in the face, as I laid in the sleeping bag, huddled against the freezing cold. I got dressed, again, got out, and started the Jeep, so it could warm up, while I broke up camp.
The jeep died, while I was in the midst of wadding up and throwing the tent into the back. I wasn't worried, since it was a 26 year-old jeep (They kind of die, once in a while, when they're that old

). I finished putting everthing in, and re-started the beast. That's when I noticed smoke, filtering through the hood. I opened the hood, and........
Anyway, I shut it down, then checked again. The starter relay had burned in two.
The worst part was, when the tow-truck driver finally arrived around 12:30, he took one look at me, one look at the jeep, and said, "YOU! AGAIN?!"
