I wouldn't say Catherine Bach was the only reason, but she sure was the best reason(next to the General Lee, although I think I prefer Cathrine and ALWAYS have, but not by alot).
The lbackout would be done to look like someone just bought a can of flat black spray and hit the chrome.
Granted the Talladega wouldn't be the most inconspicuous car, and it would be a bit of a high dollar roller for old hillbillies, it is a midnight runner to run at night, and some of them old codgers made a fair bit of money from that shine. Might stand to reason one of the more uh oh I don't know, one of them with a bit of a sense of humor and a bit of audacity, might pick up one of these.If yer ognna break the law like that might as well do it in style. I would.
As for the spoof or not, I will say this, it's his best effort to date, but it's a spoofer. Only reason I can tell is I do ALOT of photo manipulation and graphic work in photoshop, so I know what to look for, to the point of I generally don't look for anything anymore, I can just tell. This one if this was a few years ago, I would have guessed the real deal. I have to say it's a spoof though. A REALLY REALLY good one, the matching of the lighting, color balance, and color tones, is EXTREMELY well done. As is the photomatching and masking. Bar none I think it's his best work to date. Not just the photoshopping but the car is very well done.
I saw another one once it was a question of is it real or is it a model. It only had one giveaway. It was a Corvette with a rusted out body. Corvettes have fiberglass bodies. Like this one, an amazing job, but this one doesn't have any telltale signs like that one.
