Magnum P.I. (S2, Ep 15 - Try To Remember) (1982)

S2, Ep 15: Try To Remember. After waking up from a car crash while on a case, Magnum suffers from amnesia, having not been able to account for several missing hours. When the person his client hired him to find winds up dead, Magnum becomes a suspect and must prove his innocence and find the real killer. Starring Tom Selleck, John Hillerman, Roger E Mosley, Larry Manetti, Mark Withers, Kwan Hi Lim, Nancy Lee Grahm, Glenn Cannon, Clay Wai, Laurie Foi, Tony Compton, Francesca Dodge, Norm Compton and Tracy Monsarrat. This episode is a notable one in Magnum history. Not only is it an intriguing mystery - Magnum loses memory and has to piece how a client ended up dead - but it contains two new characters who become recurring characters on the show - Doc Ibold and Honolulu Police Homicide Detective, Lieutenant Tanaka, both of whom would be in it until the last series. Oh, and Robin Masters' precious Ferrari gets destroyed. Ironically it wouldn't be the first time it happened either!
