I truly saw it coming, but, was hoping I was wrong.
Too much weight on rear, therefore poor steering & control.
Actually reminds me of "Unsafe at Any Speed" (ya gotta be old to know what that refers to !!! LOL)
My middle brother had a Corvair. We would take turns hiding under the hood going to the Drive-In theaters.
FWIW - The Corvair was the daddy that led to the DeLorean. The car Michael J. Fox and Christopher Lloyd brought back from the dead, for while anyway.
