We spent two weeks with my in-laws in Southwest Florida. We spent most of the time hanging out in the condo, on the beach, and in the pool. But I made sure to visit the Revs Institute.
This is probably the best all around car museum I have visited. Others may have more cars, but in terms of the importance of each car on display, the themes, the presentation/curation, and the dozens of knowledgable docents on standby to answer your questions, this museum has it all. It's even built to withstand a Category 5 hurricane!
The "owner" is a Mr. Collier. The museum is in Collier County. His family developed much of the area, hence the $$$.
The museum's website is also worth checking out. Every car is documented with high quality photos and sometimes even videos.
The first car you see in the lobby is this green McLaren F1. That is quite a statement.
