Thanks to Dave for bringing that episode of Magnum P.I. to our attention. I found it and cut down the hour long episode to just the scenes that feature the sedan - about five minutes. The only hangup is that it is dubbed in German! Of course there's no way to follow the plot anyway, given the way it's chopped up - just check out the car!
Enjoy! http://www.honda600coupe.com/Honda_600_ ... um_PI.html
