From my readings, there were never any 4-speed factory police cars.
Whether it is an original 4-speed car and dolled as a copcar remains to be seen.
But my hunch is it's not an original copcar, and not an original 4-speed car either.
To my belief, this is not a factory PRNDL black-out plate.
Here's a plate in my 300L. I can't imagine they made a plain one just for Nupes. And this 'copcar' is missing the clear lens over top.
Mine, which shows a tiny bit of matching flash-glare across ammeter and the blockoff.
This color mismatch between dashboard and the pieces of the steering column also makes me wonder if hte steering column was modified.
The horn-button section of collar matches the dash better than the downstream pieces. Those pieces would've needed to be changed to make a AT-column into a floorshift column. I'm betting if we could see better, we'd find the big column-AT cable-shift knuckle in the engine bay.
But this detail was enough for me to not really have any further curiosity.
