I guess my point is that this storyline is really a non-starter.
The Mustang is a 2-door sports car; pretty much a niche market that has been dwindling for decades. (Hence the Camaro disappearing, reappearing, disappearing ...) The MACH-E is an electric SUV, that, by many accounts, was decently done. SUVs have been top sellers in many brands for quite some time. The EV sub-niche is even popular in SUVs now. So in summary, a popular vehicle type (SUV) with electrification (and the finance bene's which go with it) outsold a dying breed of niche car.
Duh ...
Next, should we be surprised that the Panther platform cars died off in favor of trucks?
