Exactly @HossC. Most/all of this colour interior were made by Warner Bros and had the sidemarkers/reverse light spaces filled in.
Also you can see this car has wide sill moldings (The chrome strips under the doors) which in the early seasons (Valuzets era) were painted over when they were on the car and removed by Warner Bros in the later seasons. But the biggest giveaways in that regard that its not a TV car is that it has an antenna, no vinyl top trim and clearly visible Charger badges.
I heard TV cars have some kind of number or code carved into the rear window, but I have never seen a picture of this myself.
