Well, you ended up being exactly right on this one, I think I am officially the first true victim of making that mistake.
As I got closer and passed the pick up in the left lane that was blocking most of my view of the dealership I got a rude awakening as I realized that I was looking right at a Fusion.
That NEVER would have happened with an S197, or an SN95, or a Fox, or a Gen 1 or 2 Mustang. They didn't look like anything else in the dealer line-up at the time. Really the only other Mustang that could had an identity crisis was the Mustang II, which I guess could have been mistaken for a Pinto when viewed from the wrong angle, and that would have been pretty remote.
