Detroit will always struggle to create Detroit-centric attractions. It just isn't a big tourism town. If you want large crowds going into the location where Joe Louis Arena was, it should've stayed as a major sports venue. The place was packed. I'm just not sure who will visit a historic cars museum - locals or out-of-towners? The posh hotel and the highrise towers of the Renaissance Center is indeed one of Detroit's most recognizable landmarks. It's convenience to Downtown and the River has potential, but the potential has been there for a long time without much growth.
