The 300 SL with its gull wing doors, technological firsts, and low production numbers is considered one of the most collectible Mercedes-Benz models, with prices generally in the US$1,000,000–2,500,000 range.
Sports Car International magazine ranked the 300 SL as the number 5 sports car of all time. A pair of 300 SLs for sale in 2009 were offered at over $1.3M USD from the Foxwood Collection. In 2012, an ultra rare 1955 Mercedes-Benz 300 SL with an all-aluminum body was sold for US$4.62 million at the Scottsdale Auctions in Arizona.
Designed by Daimler-Benz's chief developing engineer, Rudolf Uhlenhaut, the metal skeleton saved weight while still providing a high level of strength. Since it enveloped the passenger compartment traditional doors were impossible, giving birth to the model's distinctive gull-wing arrangement.
