Magnum's Ferrari - Red 3 litre V8 308GTSi 250 hp Ferraris with a racing clutch seen on the detective drama MAGNUM, P.I./CBS/1980-88. Owned by millionaire writer Robin Masters, the Ferraris were often driven by Thomas Magnum, (Tom Selleck), a former Vietnam veteran who headed security at Masters' Oahu beachfront mansion. Masters' manservant Jonathan Quayle Higgins III (John Hillerman) often curtailed Magnum's use of the Ferrari, but Magnum always seemed to outwit Higgins and get the car off the estate to go investigating crimes. The Ferrari's license plates were 308-GTSI (seen during the opening credits), Robin-I and Robin- 2. The price of the cars has been estimated from $50-65,000.
