Great car with great potential ruined by some California granny over speeding a cloverleaf and spinning out. Ralph Nader, a hungry lawyer, writes a book about this accident/crash, "Unsafe at Any Speed" which kills the car and gets the "Consumer Protection" bureaucrat agency started.
Most sports-minded drivers and hot-rodders bought an Empi "camber compensator" which eliminated the axle-tuck/rollover thing. Had GM limited the wheel travel it never would have been much of a problem

The engines these days are quite popular with home-built aircraft people... big power at less money...
