The driver of the truck saw it come off and bounce down the road behind him. He did stop. When he told Teresa that there was no way it could have done the damage to the floor she told him that she wanted to call the police to file an accident report.
Lesley (my granddaughter) is still swollen and sore. They took x-rays and said nothing is broken.
After getting the Sebring up on a lift we saw how spooky the damage really was. Underneath the big hump in the carpet was a 6" diameter gaping hole. We were lucky that the hitch hadn't come straight through the floor at 60 MPH. Farther back there was a 12" slice through the floor in the back seat area that had even cut through the carpeting inside. Further back yet you could see where the hitch had struck the exhaust resonator. Naturally the aluminum oil pan was toast. There was also signs of a very fresh oil leak on the cam seals. (no traces of any old oil anywhere around that area, but fresh dripping from them)
Teresa and I aren't destitute but we don't own any credit cards or carry collision insurance on our vehicles (only liability and comprehensive coverage). We couldn't rent a loaner car around here for those reasons. As many dang cars as I've got around here you'd think I'd have a spare one to use. - But until I get the Barracuda running better, we're down to just the pickup. I guess I'd best get some of these projects completed already.
The next time I get a chance to snap some pics of the underside of the car I'll post them. I didn't have a camera with me when we stopped at the garage.
