Those pics are awesome. What color is the 2015? I like the dark green hues.
I´d say in the end beauty is in the eye of the beholder. Mustangs have changed so much in all these years that the "it doesn´t look like a Mustang" is really subjective. The change from a 65 to a 71 was very drastic. then again from 73 to 74, yet the 74 had a lot of hues from the 65. Then the 79 compared to the Mustang II was completely different... the 94 from the aero fox...
Yet all of them are Mustangs.... they all share some basic proportions and the driving position and the way they drive...
