Show us that same picture from the rear. It's not the front that is the problem with the newer Mustangs.The worst of 1970s styling was the Mustang II IMO, big bumpers, padded vinyl tops, ect. I just like to dispel the attitude many Ford fans have in that the Mustang should have undergone some sort of styling evolution akin to the Porsche 911, despite the "sacred cow" 64-1/2-68 lasting only 3-1/2 years. We as MN12 enthusiasts should know considering the Tbird not only abandoned most of it's original styling immediately, it completely changed segments.
I'd take a 71-73 over a 05-14 stylistically any day of the week. "Big" and "bloated" is subjective I guess...
