Nice to see more and more of the old GM concept cars being pulled from the woodshed and restored. If the experimental rear engine layout worked out, who knows where the corvette would be today. That cantilevered layout (like VW and Corvair), except with a heavy cast iron big block Chevy engine, was likely what killed it.
Interesting to read that it was crashed after a double-lane change maneuver during testing, repaired, then parked, and eventually given to Smokey Yunick to 'cut up for scrap'.
Not many know that the Ford Mustang started out as a concept mid-engine layout capitalizing on Fords already in production (at the time) V4 engine, that almost made it into production. THAT would have been an interesting car, for certain.
Thanks for sharing, Tom
