Just spent the day at the Revs Institute in Naples, Florida, a museum dedicated to automotive research and historical study.
We were given a guided tour and saw many spectacular cars from 1898 to the late 1980s.
Each car was separately presented (not crammed like many museums), with no ropes separating viewer from vehicle (but with a strict "no touching" policy).
It was well worth the drive, and worthy of a second trip in the future.
