I donīt think thereīs anything wrong with the family resemblance, to my eyes it doesnīt look like a Fusion. Yep the grille shape but thatīs it, the Mustang has a clear "Mustang" look with the bulky hood and aggressive front end. And if you look at a Fusion, Taurus, Focus and Fiesta, they all look like different cars despite sporting a familiar look. I actually think the Fusion is one of the best looking mid size cars, wouldnīt mind owning one.
Back in the "New Edge Design" Era in the early 2000s all Fords had the New Edge Design, yet they were all very distinct (and I think the New Edge Stang is one of the best looking Modern era Mustangs).
To my eyes Mustangs never loose their "coolness" even when the new models arrive, the old ones are still terrific cars. I donīt think the 2015 is going to make the 10-14s look dated at all, just different.
I think the 50th anny car is going to sell like hot cakes...
