I actually saw one of those on the road last summer! I was driving in Kansas City, MO on "Ward Parkway", and spotted one on the other side of the divided Blvd after being pulled over by the police! I doubted myself at first, but gave it a closer look and it was unmistakeable. Really a wonderful looking car, and unmistakeable in appearance.

Probably a dealer car. Wonder what he was pulled over for.
