Possibly. Only some disassembly and researching the car would tell us what the car did and didn't come with. Not all cop car details are listed on the tag but could still remain on the car. Have you found a broadcast sheet in the car? That would help.
Here's what we do know...with the exception of the L instead of a K in the VIN (PL vs PK), the rest of the tag contains items consistent with PK code police cars (the interior code, the VON, the Y39, the special handling tag). It's pretty safe to say this was a fleet car of some kind. Without doing some research, we do not know who ordered it and for what purpose. We do not know for sure from what's in front of us that it was or was not used for police or law enforcement work. A little research on the car might give us more clues.
I must say that a black car with a gold interior would be an odd combination for a police car.
