The Edsel, like the Corvair, got a bad rap.
It wasn’t the car (which was quite innovative), it was the marketing.
The Edsel got the bad rep because it overheated; an Edsel collector I know really likes his (and all the other “orphan” vehicles in his collection) and said the cooling system fix had to be done to any of them that didn’t go to museums, ie, if they are to be driven, the cooling system mod (whatever it was) has to be done.
