Ecto-1 (Ghostbusters)

Ghostbusters' Ecto-1 not only has a memorable look to it (especially considering it's a converted ambulance/hearse) but also has a trademark sound. Who can forget as the hilarious team of paranormal investigators and ghost catchers come barreling down the street with the "No Ghost" logo and sirens blaring as the awesome theme song plays over the scene. Who you gonna call, indeed!
