I'm a Mustang Enthusiast, and I am receptive of the idea. Depends on their treatment of the basic Mustang outlines......
More likely, this one will be a stillborn design idea. Ford already has the Escape and Freestyle to cover the small, sporty or "crossover" SUV/wagon market. All this proposal will do is piss-off legions of Mustang fans. But then, the Ford Probe *almost* replaced the RWD platform and became the Mustang back in the '80s. This elicits the same response: Blech!
