Midwest Museum opinions

Going back to OH soon for the last time in a long while. Time will be limited, but I'm hoping to get in a couple of museums while out there if I get the chance. Anybody got any opinions on the Auburn Cord Duesenberg museum? Also want to take the wife to Henry Ford Museum and the Motown Museum- anybody been lately? Worth the trip and how much time should I allow?

Thanks
Gary

I love the '37 Cord 812 and own an unbuilt model of one that I've been told is extremely rare. I have been in touch with cord owners who have raved about the museum as one of the better ones!
