Restored to factory specs, this rare 1955 Mercedes-Benz 300 SL Gullwing is expected to bring up to $2.2M at Monterey.
A meticulously restored 1955 Mercedes-Benz 300 SL Gullwing Coupe, widely considered one of the most iconic sports cars ever built, is expected to draw significant attention when it crosses the block at Broad Arrow Auctions’ Monterey Jet Center sale on August 14, 2025. The car carries a presale estimate of $1.9 million to $2.2 million.

This matching-numbers Gullwing, chassis 5500409, retains its original engine, transaxle, and body, a critical factor for collectors who prize authenticity. Finished in its factory-correct Silver Grey Metallic over a Blue vinyl interior with plaid fabric seat inserts, the coupe is a textbook example of Mercedes-Benz’s most celebrated road car of the 1950s.

Born from Mercedes’ racing dominance with the W194, the 300 SL made history as the first production car to feature direct mechanical fuel injection, propelling its 3.0-liter inline-six to 215 horsepower. With its lightweight tubular frame and distinctive upward-opening doors, the SL could reach speeds up to 160 mph, making it the fastest production car of its time. Only 1,400 examples were built between 1954 and 1957.

This particular Gullwing has been the subject of significant investment, including a $280,000 restoration by Mark Allin of Rare Drive, Inc., completed in 2015. The extensive work included a complete suspension and rear axle overhaul, rebuilt braking system, and a cosmetic refresh that returned the car to its original specification. Rudge-style knock-off wheels were installed at a cost exceeding $40,000, further enhancing its desirability.

In March 2024, the car underwent additional servicing at the Mercedes-Benz Classic Center, which included tuning of the fuel injection system and a fresh set of Dunlop Sport tires.

With its elegant restoration, comprehensive documentation, and iconic design, this 300 SL represents a rare chance for collectors to acquire one of the most revered sports cars of the 20th century—one equally at home in top-level concours events or on the open road. See it here.
