Virtually every auto maker in the world has one particular model they're truly proud of, with the big names having many defining models to choose from, but even the greats blunder greatly sometimes.

It's almost like Shelby was sick of style and speed, so he went looking for the safety and comfort of a sedan but didn't know quite how to make the transition.
The Ford Mustang II had a similar problem making the transition from being a macho muscle car to being seen as the brown corduroy bell bottoms of the automotive world.
