This ran for five seasons, from 1985-89. I don't remember it well, and I'm not sure how much of it I even saw, but I'm sure I liked what I did see of it. It was a dramedy about a pair of mismatched private investigators, the high-class former model Maddie Hayes (Cybill Shepherd) and the more flippant David Addison (Bruce Willis). And the show was rather famous for the sexual tension between them. Hopefully someday I can see the whole series and write up a proper review.
