I attended a car show last summer and parked our 2015 GT 'Vert next to a 1967 Mustang
. Walking around both cars revealed to me many styling cues from the '67 that appeared in our 2015.
These cues are subtle, I'll give you that --- but still unmistakable if you look carefully and pay attention.
The suggestion of the side coves on the 2015, the segmented tail lights, the creases at the top of the front fenders, the angle (slope) of the hood, the overall proportions, the angle and shape of the bumpers..........I really enjoyed seeing these two parked next to each other and it was very revealing.
