Both of my Thunderbirds do. They are R GO and AR GO respectively. For those of you in America you would not understand these plates, as they relate to an old puppet show that was on tv called The Thunderbirds. The catch cry was, "Thunderbirds are go" hence my plates. Many a head scratching at car shows trying to figure it out, turns into that light bulb moment when they do.
Those of you who did know the show, have also worked out my user name as well....Lady Penelope was the female star of the show, and as I have named my '60 Penelope, that did me for a handle.
