Highway Patrol

Radio Motor Patrol (RMP) is a term used to describe the patrol cars of the New York Cidy Police Department (NYPD).

A NYPD RMP had a short and thankless existence back in 1971.  A 440 cid Mopar Police Pursuit vehicle made no sense whatsoever for the NYPD as most RMPs patrolled at 10 to 15 MPH.  These cars were stripped-down with no options, no prisoner cage, a six-cylinder, warning lights, roof-mounted siren and an analog Motorola radio.  

They ran 24 hours a day and after four years were completely used-up, sold for scrap  or busted-up for parts.  

Which would explain why this vehicle is not a restoration - it is a replica.  You can read about it here.
