While I obviously can't comment on how the new Interceptor performs in law-enforcement duty, I can say the following:
1) It's not good looking. It looks like every other POS FWD car on the road today. (That may actually be a plus for the police)
Beauty is in the eye of the beholder. However, the Taurus does appear similar to some of the other cars on the road today. Once you get attuned to them, you can spot them easily and pick them out from a crowd from the front, side or rear. The car has a natural rake to its body design.
2) It remains to be seen how the uber-complicated twin-turbo Eco-Boost engine will fare with 100,000 miles of patrol duty on it, not to mention how much it will cost to maintain vs. its predecessor.
I don't think many of the police departments are getting the 3.5L Ecoboost engines that come with the SHO. Most PDs are getting the regular 3.5L. The one LEO that I spoke too in PWC said that he likes the new Taurus but would have liked to have the V8 option ??? WTF ??
3) Actual LEOs I have spoken to about the car all say the same thing: it's too damn small.
I actually think that the Taurus interior is larger than the Marauder. The back seat leg room is definitely large. The trunk on the Taurus will hold 50% than the MM. The front seat room may seem crowded because of the wide console that sits about 4 inches taller than the MM. Some people have said that it restricts legroom. I have not noticed that problem at all. Must mostly affect those who drive with their legs spread open.
The neighbouring town of Falmouth MA has a couple of them, but most of the other departments around me are either keeping their CVPIs as long as possible or buying Chargers.
