In the American TV show 'Magnum P.I.', what make of car does Thomas Magnum drive?

Robin Masters' red targa topped Ferrari is the classic Pininfarina-styled 308 GTS model (1975-1985). There were three different 308 GTS's used during the show's run. In the first season, the Ferrari was a 1978 308 GTS (one mirror, no rear spoiler, no front hood vent, red vents behind the headlights). For the second and third seasons, it was a 1980 308 GTSi (two rectangular mirrors, black vents behind the headlights). For the rest of the series, it was a 1984 308 GTSi Quattrovalvole (black vents on the hood and a black spoiler on the rear of the roof panel).

The Ferraris used in the show had to be specially modified to accomodate Tom Selleck, who stands 6'4" tall. The padding was removed from the seats so he would sit lower in the car, and the seats were bolted as far away from the steering wheel as possible to maximize the leg room. Even with these modifications you can still see that Selleck's head is higher than the top of the front windshield frame! You very rarely saw Magnum drive with the top up.

The producers originally intended to use a Porsche 928 and asked Porsche to produce one with an extra large sunroof for aerial shots. Due to a strict policy by Porsche of not doing any special specifications at customer requests, the Ferrari 308 GTS was chosen instead and went on to become one of the most iconic cars of all time.
