Corvair was a decent car. Its first year did have an independent suspension set-up which proved to be not well thought out. Come to think of it, US Army Jeeps of the mid-1960s-'70s (M151)
had a similar suspension, with similar results, if I recall correctly. Anyways, GM corrected the suspension flaws, and the car drove very well after that. For any who've ever driven a Porsche 356 or early model 911 -- or a VW Beetle -- the Corvair's handling was alright: it was the drivers who were deficient.
That and Ralph Nader's integrity.
