Clint Spevak As Mark noted, I was and am NOT the body structure expert about Crossfire. But can certainly confirm that substantial structure was added to the lowest parts of the roadster body. There was bragging at the time the roadster version was introduced about the convertible having several times more torsional stiffness than the (intact) coupe (and higher stiffness than perceived competitors at the time), due to the additional parts added. As an even more every day practical concern than what would happen in a crash: how would such a modified couple body keep the door openings from closing up, preventing the doors from operating? Would be interesting if anyone has a clue about the source of that Instagram photo (from August 2016) to report on how the car survives now - or not.
