Fire next to my workplace

So I'm coming back from a test drive and see this fire in the boneyard of my towns local towing business across the street. Normally seeing black smoke is no big deal since they have 5-6 large diesel trucks back there and some heavy movers they start up and move around. Plus they just burn shit sometimes.

5 min later I come to this monster fire, but I don't hear anyone screaming or freaking out or acting like it's out of control.

My co-workers and I finally think to go up on the roof and get a better view. Not sure how they managed to flip that car and set it in fire, maybe they were cutting the cats off the exhaust or it was dumped like that and something shorted and started a fuel leak of fire.

While we were up there we could see and hear the local fire department and police vehicles coming from all directions. Took them 5 min to get it out. I'm guessing there was an electrical reason the fire started because after they sprayed it with water there was white foam everywhere. After all, no one got hurt. Everything important seemed to be undamaged by the fire. Hopefully they get a break on the bill since they let the fire dept train the newbies how to use the jaws of life on their junk cars.
