My Aunt had a Duster, I'll never forget that beast of a car. She'd take Me places and I would bury My head in My lap. (Embarrassed). Imagine that!
One day she looked at Me and said you know what? This car can outrun any car on the streets no matter how pretty they may look to you!
I was sort of like 'yeah right' she told Me (and I am not sure if this is true or not) that it had a 'police package' in it. Didn't even know what the heck she was talking about back then.
She said a cop owned it prior to her owning it and had some uhhh modifications done on the engine.
She told Me some wild stories about that car and maybe, it was her that made Me appreciate Mopars? No idea but it's quite possible looking back on it now. She proved many times that the car had plenty of 'get up and go' and nearly scared the pants off of Me a few times.
I did find this link about your query as far as police package cars are concerned.
Police Package Cars Pop Pop (husbands grandfather) had a Fury police car. Husband says the man was dangerous in that car. He owned one of those what, ummm....Sinclair stations and was a mechanic both in the military and at home.
He would always be looking in the back seat for something or looking over there, over here, over there while driving that black wonder. Never wrecked but hubby says he was scared plenty of times.
Said that car was wicked. Wicked enough to never be wrecked. Never was either. (Don't know where it ended up so I could be wrong by now).
