While flipping through a magazine the other day, it suddenly occured to me that the Tribeca looks unusually similar to the 1958 Edsel - a car infamous for it's looks and sebsequent failure.
The similarity is most shocking on the front end. The Edsel's "horsecollar" grille is taller and tapers the opposite direction, but it's bold and front and centre in both cars. Also, it's flanked by smaller grilles that span the whole length of the front, with the headlights sitting on top.
If this wasn't enough, the Tribeca's taillights are also very similar to the Edsel sedan's (the Edsel wagon's were completely different) - the narrow and wide, set up near the bottom of the greenhouse.
