Founded by Hot Rod magazine publisher Robert E. Petersen and his wife Margie in the mid-’90s, the Petersen has a stellar collection of cars, motorcycles and all things related to the automobile and American car culture. On two levels of the 300,000-square-foot museum (which takes up an entire city block in the Los Angeles Miracle Mile area near Beverly Hills) you can see approximately 150 different vehicles on display, ranging from famous movie cars and classics to historic hot rods and significant designs from vehicle manufacturers around the world. But there are many more vehicles, around 400 total, in the museum’s collection. Where are the cars that are not on display? They’re kept in The Vault, which is a nice way to say they’re in the basement storage warehouse, underneath the museum’s main floor.
