This car is now listed by the same auction company that became RM Sotheby's in the mean time, for sale on August 13 in Monterey, lot 109 estimated $ 5.5M.
It is in great condition with matching numbers and includes many factory options.
I republish below my 2012 post introducing this model which was the very best of post war commercial Mercedes-Benz. The video linked here was shared by RM before the 2012 sale.
Introduced in 1952, the 300SL by Mercedes-Benz had all the qualities to seduce lovers of fast and powerful cars. 300 means a 3-liter engine, and SL (Sport Leicht) is a skilled summary of the targeted market area.
In 1955, the third type of chassis used in the 300SL is the W198. Two important innovations appeal the fans.
One of them is aesthetically spectacular but ultimately quite surprising. Gullwing doors have their hinge in the axis of the roof. Access to the seat is not really easy, but it allows rainwater to pour on the passenger's head when he gets out of the car. Yet this fantasy spanned three years of production.
Another innovation is more interesting, but provides a significant additional cost. The body, usually offered in steel, is also optionally available in aluminum alloy.
Only made in 1955 and finally limited to 29 units, the Mercedes-Benz 300 SL Alloy Gullwing saves 80 kg compared to the basic model. It is the only production car whose performance can compete with Ferraris in the eyes of the wealthy customers wishing to mix sport, road ... and glamour !
On 20 January 2012, another 300SL Alloy Gullwing was sold for $ 4.62 million including premium by Gooding in Arizona.
