The good Doctor's Foundation Museum is indeed incredible. I'm lucky to be only about 1/2 hour drive away, and thus can go almost any time.
I have heard Dr Simeone speak about the Coupe on quite a few occasions, he is pretty low-key about how he bought it. IMHO, he would prefer not to deal in hype or drama - just the cars and their important history. Promotion of the Museum is likely needed to keep attendance (and a few $$) flowing in.
