Based on feedback here's the latest. The side view and D1 are the same setup. D3 has the fender flares and raised rear fender hip as requested.
I gave the D1 views bronze colored wheels which I think helps warm up the look of the car. I put the traditional 3 vents on the side in front of the rear wheel. I also move the front door line forward as requested to lengthen the door.
I've struggled like crazy with the roof line on the side view. You wouldn't believe how easy it is to move a line just a slight bit and suddenly you've gone from a Camaro to a Mustang fastback. I'm not entirely happy with the location and side-view profile of the cabin. I've moved it forward, backward, up, down and I still can't find that sweet spot where it looks "right". But hey... it's a work in progress.
