Was the red Acura there when you parked or did they show up later?
I'm wondering if the following is possible...
Red Acura gets ready to leave and accidentally goes forward instead of backwards, nudges over teh 'vette, but, something under the car catches on the seam between the bumper and hood or an emplem or, something... The weight of the car on the nose of the 'vette helps to take weight off the rear wheels, add in the wet pavement and now it's no so difficult to move the 'vette. Guy starts trying to back up but is stuck to the 'vette, gives it more gas and nothing happens, then...
the rear wheels with the reduced weight break free and the Acura and the 'vette go flying backwards still connected into the Explorer.
This would explain why there is no damage at all to the rear of the 'vette and why there is minimal damage even to front although based on the damage to the REAR of the Acura and the Explorer there was enough speed to do damage.
Anybody willing to go with this one???
