Now here’s a rare birdie. A loaded ’78 Diplomat wagon. Sure, most of you likely remember Diplomats and Gran Furys from many ’80s movies and TV shows, but the wagon didn’t last long. 1981 was the last year for it (and also the Diplomat coupe); from then on, you could get only a four door sedan.
And of course most of those four door sedans sported various law enforcement regalia or were painted yellow. The Diplomat was introduced in 1977 as a more upmarket model, playing off the ‘small but luxurious’ style brought into being by the ’76 Cadillac Seville.
