i'll share one of my stories. my uncle passed away in 1991. at the time he had two cars. one was kept by my aunt as a daily driver. the other was his Cadillac which was garaged for years after. my cousin buys the car from her in 1999. anyhow we go there together to pick up the car. Its a monday morning-about 2a.m. i'm driving, about half way through the trip, the rear floorboard and seats suddenly start burning and erupt into flames so we pull over immedietly, turn the car off and start putting out the fire quickly with our jackets. anyhow we ripped out all the carpetting and pulled the seats out in search of the cause, and came up with nothing.
so we start the car and start driving again, a little freaked at this point. we get in front of my building and both step out the car for smoke. the car was idling fine, when all of a sudden it was as if someone floored the throttle pedal for about 3 seconds, then it went back down to idle and turned off. so we turn the car back on again..it idles fine for a bit and then does the same thing. after that, it didnt want to start anymore, so we popped the hood to find that there was no battery in the car. at that point we had the car towed back to the garage it came from, and has been sitting there since. i still have no explanation and dont know what to make of this today.
