"The BMWs, which carry a list price of $119,900"
you can be quite sure the bacon aren't paying retail for em.
There is no State duties or taxes paid by the Police when they buy these, just federal.
They will be getting them as a Lease Vehicle anyway, so they won't pay full retail by any stretch of the imagination.
Plus they'll come with a lot of gear on them without having to add it in after purchase.
Radio's will be something that will have to go in after they get them, and they get recycled from one to the next.
I'd be interested in what they go for at Auction, after the boys have beaten the daylights out of 'em.
