i know a plank that jacked his polo up via the fuel tank, he wondered why it had started leaking until I pointed out his errorReminds me of a mates Mk4 Cortina he asked me to weld a cracked rear floorpan on, I jokingly told him to use Araldite. The crack was in the filler covering the huge dent where someone had jacked the car up on the floorpan.
Looks like a bracket of some sort at roof level and in the picture of the yellow Cortina the person sticking out the window appears to be behind an upright bar
