Ford's new interceptor Police Car

I've actually been looking for a used 'family' car, something comfortable with plenty of room, I'm getting tired of driving a pick up truck and there is no room for the family.
The other day I started looking into used cop cars, and the Crown Vic seemed to be the best candidate, for some reason all of the Caprice cop cars around here are totally trashed.
I like the extras they come with, and even the steel wheels for all of the potholes- the best part is the rubberized floor.
Carpet is a joke in any daily driver, who thought of that anyway?

Anyone know the gas mileage on these cars?
