The Edsel's main reason for downfall (IMHO) was; Introducing a new model car in a recession. Every car brand was experiencing lower sale numbers. Just, as the Edsel came out. Perhaps, if Edsel had been introduced as, sales were increasing (say 1952?), rather than when, decreasing.... the story might have been different. Something that did come from Edsel, was; The MEL engine. The MEL is, a very fine powerplant. Powering Lincolns up until 1968.
