This is the Mercedes-Benz SSK, built between 1928 and 1932. With a top speed of 120 mph (190 km/hr) it was the fastest car of the late 1920s, and most of the forty or so that were produced (yes, so few!), were used as racing cars and destroyed that way. Now there are only four or five remaining with totally original parts, and around 100 replicas with parts from original vehicles. Wiki informs me a 1929 model auctioned at Bonhams in 2004 sold for 4.17 million GBP (around US$7.4 million). That makes it the second most expensive motor vehicle ever sold in history.

Ralph Lauren has in his private collection a 1930 model known as the Trossi Roadster, which he had meticulously restored and flaunts a pretty dramatic body. It’s a Batmobile if ever I saw one. Read about this wild car here.
