Aside from the Cords, Auburns, and Duesenbergs my absolute favorite was the Virgil Exner Design cars, beautifully finned and detailed mid-50s Chrysler products. I've never seen so many in one place, funny that the DeSoto brand died in spite of some really clean design on the cars back in the day.
Of course a car show isn't a car show without some outrageous custom cars. The most outrageous aside from the Hot Wheels Darth Vader car was the BWM Isetta L.A. Lakers tribute car.
Of course this is just a sampling of the images produced at the Palos Verdes Concours D'Elegance. All 290+ can be found on flick in an album.
The day before the Palos Verdes Show was the equally entertaining Street Rods Forever show in Monrovia. This annual event iw well attended and the biggest in the SGV. What you give up in terms of curation you get in terms of absolute variety of customs, restored and survivors in a mishmash along a 1/2 mile long stretch of Myrtle Avenue in historic Old Town Monrovia. I haven't missed a one in nearly 20 years. Its That Good.
Of course, these weren't the only cars I shot. some 150+ images can be found in a flickr album.
