Continuing with cantsin's point...
Magnum, P.I. did fail constantly, yet somehow the Ferrari made it worth the trouble. Occasionally Magnum's buddies T.C. (Roger Mosley), the chopper pilot, and Rick (Larry Manetti), the bar owner, would help. Unfortunately, Rick was an alcoholic with serious commitment issues, and T.C.'s helicopter was grounded in the mid 80's for being horrendously ugly.
Oh and Magnum often got his friends killed off to star on other short lived shows.
