What’s with the rear spoiler?

That color makes the body pop.

Yeah it took me a long time to get the color on my car the way it is. It’s a custom color. It’s very close to that Chargers.

I don't recall that color ever being offered on B's or if it was it wasn't very common.
I have seen on lots of A body's. It looks good on a big car, relatively.

it was an option available J81 from the factory. No functionality, it was added for looks only. Some people like it and some don't.

I agree, it doesn't add to the look. I would never add it and if I bought one that had it, I would remove it.
