1955 Mercedes-Benz 300SL Alloy fetches a record $4.62 million

If not for US importer Max Hoffman and his passion for a sports coupe based on the highly successful W194 series race cars, the Mercedes-Benz immortal 300 SL line would never have come to production.

The racing success of the factory team was having a positive effect on Mercedes-Benz sales in the US. However, without a car clearly related to the race-winning machines, the marketing advantage of the immensely costly racing effort was limited. Accordingly, Mercedes-Benz management approved the 300 SL project after Mr. Hoffman’s firm made a commitment to purchase 1,000 of the cars for US distribution.

Integral to the marketing plan for the groundbreaking new sports car was the expectation that the cars would be used for competition by private owners in order to bolster sales in the showrooms, and the factory ensured that the 300 SL was accepted by the FIA for international competition.

As a result, the production Gullwing could be ordered with an all-aluminum body. When chosen, many additional competition upgrades followed suit. A competition camshaft was fitted along with stiffer, shorter springs that lowered the car and enhanced peak performance, while racing-specification tires on wider rims promoted better adhesion. Plexiglass windows and vented brake drums were also featured in the package. The cars were nearly 200 pounds lighter than the standard steel-bodied version. In all, just 29 of these aluminum-bodied cars were ordered and built – approximately 2% of the total Gullwing production.
