Oddly enough, I don't hate that AMC. In fact, I kinda like most of the AMC designs (each in their own way are pretty cool).
I've also thought the same thing about our Mustangs - why do the door and quarter windows have the slight declination 2/3 of the way back on the opening. IMHO, they should've kept the door to quarter window transition straighter with no decline - it would've gone even further toward the "looks fast standing still" reputation our cars already have, and contribute less to the "tail dragger" look when the car is sitting perfectly level.
As well, the late '30s, '40s, '50s, and early '60s is not an era I'm particularly fond of. All of the cars from those days were bloated and bulbous-looking - I'm not a fan either, Dana. Disclaimer: I am, however, a fan of well-restored and/or cared-for examples of any model from any era - just not so much the style and design of said vehicles. As an enthusiast myself, I can certainly respect the blood, sweat, tears, love, and money that goes into keeping the dream alive, and try to do my best to never take that away from anybody.
