Very nice car! Looks mostly complete.
Looking at the pictures I'd say its a replica. I don't have VIN numbers to see if it was a screen used one but I very much doubt it. All cars who were 'send away' after being used on the show had the roof portion with the flag/text cut off and the remainder after the show are almost all well documented.
Yes, I say Almost, but there is nothing really which indicates this car could've been a TV car.
Things to look for in a stunt/second unit car is a fully spray painted interior and no orange under the hood. On this one the interior seems to be nicely done for a non official Dodge colour with the exception of the steering wheel. Like TV cars this car has been painted to orange on the exterior only with the engine bay and probably trunk being in the original colour. The exception here is that they painted the hood hinges. Which was too much work for the show on a stunt car.
For a close-up/first unit car they'd have the engine back blacked out. Which looks like someone had actually done! But very crudely looking at the hood hinges. It's not something you wanna look at closely with a camera on a TV show.
I could go on, but I doubt it'll add much.
Did you find the broadcast sheet? Anyway, very nice Charger either way! Keep us updated on the car if possible!
