The main character Judge Advocate General attorney Commander Harm Rabb drives a red '69 Corvette small block convertible. You only get to see it occasionally, and usually not too much detail so as to know more about it. However, the Corvette connection is there and occasionally another character for that week's show will show up in a Corvette, usually a newer one. On an episode about a WWII Navajo communications operator whose remains were just recently found, the lawyer for the Navajo Nation drove a silver '98 convertible. Several Corvettes show up here.
Most references are reasonably accurate, but mainly due to memory, which can be off.
