The Peterson Museum was on Jay Leno's Garage last night (DAVE channel). They've got all sorts of wonderful stuff but have some non-exotica, a Chrysler Neon and a Trabant among others!
Yeah I saw that too, we didn't do the vault tour, but I suspect some of those cars might be down there as well. Ironically the Pink Honda S2000 that was in the show, is now on display in San Diego, so I think they all must link and rotate the cars.
