Yeah, BMW's were everywhere and a favorite for making into car bombs. Responded to one that blew up on Route Irish just in front of the ECP targeting a Rino bus that was traveling back from the green zone. Barely hurt the bus but there was nothing left of the BMW except for a alternator and disk brake all warped and distorted. It blew out windows of the locals 400 yrds on either side of the Highway. We were about 8 blocks away when it went and felt it through the ground hard. I thought the challenger may have been trapped as well since that area was a favorite for launching rockets at the base. Might have risked it to take a look, I mean I searched over 1000 vehicles in random patrols and snatch and grabs and any one could have been a car bomb, actually found a volkswagon with the taxi cab orange fenders that was being made into one just didn't have the explosives yet , ( normally 3 to 10 artillary round rigged ) when it's your time it's your time. Guy driving the car failed swipe test for explosives and nitrates.
