I was there, the entire Kingston collection was owned by Dana Mecum.
That car was rough, paint was not very good imo. That one "sold" along with the blue challenger T/A, then they vanished from the entire collection list. The other 19 are still listed on the Mecum site , and I believe they are actually sold. I was shocked at what the Superbird did, no matching #s and not in the best shape.
