I had a similiar incident with a cop in Pinal County, AZ. He pulls in behind me at a local gas station while I'm filling up and

Cop: Is that a new Challenger

Me: Yes it is

Cop: that's a limited edition so what number is it

Me: 904

Cop: How did you get one?

Me: What?

Cop: I thought only the the very well to do would get LE version

Me: I'm doing ok

Cop: so where do you work.

Me: Where I work has nothing to do with this car I pay for it out of my retirement check.

Cop: Retirement, you're not old enough to be retired

Me: Officer while your mother was changing your diaper and walking you to school I was standing on the front line of freedom at places like the Fulda Gap and the DMZ. I earned the right to drive this car and I have the financial means to do so. Have a great day

Cop: You too and thanks for your service.

I see him all the time and he just waves.
