I had a 1960 Corvair and they were unsafe to drive. If the streets were slick and you went around a corner too fast, your rear end would get there before the front end.

Too much weight in the rear because of the engine. I got mine in 1970 for $225 It ran well until I did not notice I had a transmission leak and trashed the transmission.
Also the heater did not work very well and it had no A/C, or power anything.
I think Sea Dog was looking at Convair and wrote Corvair.
He's an abstract thinker like myself.
