What if Ford had further developed earlier Thunderbird design cues such as slim rear quarter windows and rear fender skirts on their almost-a-fastback 1970 model? I pushed the front wheels forward several inches for a shorter overhang and more classic steering wheel-to-axle proportion. As extreme as this looks, it's just about the same as the classic Continental Mark II of '56-'57.
Photos of older cars are harder to find than press photos of new cars, so I'll take what I get as long as the resolution is adequate. This car had seen better days in the original, so while I fixed a few flaws in recreating it, I kept the look of a slightly used car. I'm including the original photo below to show that in addition to the changes to the car, I "touched up" the background as well. There was something about the car that screamed for graffiti, which I found on a photo of the new Kia Optima. I also deleted the apartment building in the rear and added a canopy of trees for that "tree grows in Brooklyn" look which I find so appealing.
Original image of a fading glory, a white 1970 Thunderbird standard coupe, which I found through Google Images. Even in less than mint condition, vintage Thunderbirds have a glamour about them that doesn't fade no matter how much the paint does.
