I tell you what, I will take one of each of the cars you described. Then all will be settled.
You are way past me on all this, I know I saw two HO Lemans and that is the only for sure part. I strongly believe they had the 455 emblem, maybe I can get down and take some pics. Both are still here.
This yellow car that started this thread is one sharp ride, and I would die to have it.
