Okay, hard to beat Daisy Duke but this is rather topical because I was just watching a couple of old classic movies: "A White Christmas" and "Its a wonderful Life".
In White Christmas, they show a Jeep (Willys MB or Ford GPW?) somewhere in the European theatre and then again later in the states. I guess they are implying the general kept the jeep when he retired to the states.
In "Its a Wonderful Life" there was just a random WWII era Jeep.
