3 or 4 years ago CHP had a few (not sure of the total number)
Chargers. They were not happy with the reliability, so I'm surprised to hear they ordered a couple hundred of them. But I've been out of the state for a few years.
Frankly, I don't think visibility is as good out of the Chargers. The PIU has better visibility and more space even though it's still on the tight side and I'm not even that big a guy. The Chargers do have more trunk space than the Ford Intercepters, though, imho.
