I have two original P1 Interceptors both 2014, one has 27k, the other 11k, the lower mileage one has never been in police service.
Both have the ecoboost engine. I looked for almost 3 years for an interceptor with the ecoboost engine, then found two OF THEM. One has the Ford "ready for the road package" that has lights hidden in the grille and alongside the center brake light in the back window. (all disconnected) One of the cars has ballistic front door panels another 3k option.
Ecoboost engines are rare in police cars, partly because it's a $3050.00 option.
If you need any
