Mine was a 70' Ram Air IV Judge convertible ...
A white, completely unmarked car. No Pontiac, no GTO, no Judge, no nothing. Just white with a white top and light tan interior. Original owner special ordered it that way, and I bought it off him with six thousand miles on it.
Even had the factory vacuum operated exhaust cut out under the dash. Push the walnut knob in and it sounded like a Bonneville, pull it out and it sounded like a dragster. Today that option is worth about 30 K to a car.
Sold it when the oil embargo hit. One of my top three stupid things I've done....should have just stored it.
