In March 1957, Mercedes-Benz unveiled the 300 SL Roadster, employing a host of mechanical advancements and stylistic revisions to create a new, open version of the successful Gullwing. Chief among these were a new rear-axle design that improved high-speed handling and a modified space-frame chassis, which allowed for conventionally hinged doors. The new Roadster offered improved ingress, roll-up windows, a useful trunk, and of course, the thrill of high-performance open-air motoring.

In total, Mercedes-Benz built 1,858 examples of the 300 SL Roadster, steadily updating the model until production ceased in 1963. Among the most collectible Roadsters are those built at the very start of production, which contained carryover Gullwing components and unique, hand-tooled features, and those completed at the end of the run, which had alloy engine blocks and four-wheel disc brakes.

The 300 SL presented here, chassis 7500038, is particularly noteworthy, as it is the second production Roadster built. According to a copy of its factory data card, this car was completed in March 1957, fitted with body no. 7500002 and engine no. 7500036.

According to the Daimler-Benz archives, 618 production Roadsters were made for the 1957 model year. Of these, only the first three – chassis 7500037, 7500038, and 7500060 – used 1957 Gullwing chassis numbers and were built prior to the standard Roadster chassis number sequence, which began with 7500080 and continued, uninterrupted, through 7500694.

When new, this 300 SL was elegantly finished in Elfenbein (Ivory, DB 608) with red leather upholstery and a black soft top. Optional equipment included a Becker Mexico radio, fitted luggage, driver-side rearview mirror, and US-market lighting and instrumentation. The car’s build record also carries the important notation “Internat. Automobil Salon New York Standwagen,” indicating that this Roadster served as the official New York show car. As the 1957 show was held during December 1956, 7500038 was likely retained for promotional duties and displayed at the 1958 New York International Auto Show, held April 5–13.

Two weeks later, on April 30, 1958, the 300 SL was sold to its first private owner, George R. Hill, a businessman living in Mahwah, New Jersey. After Mr. Hill’s death, his wife Henriette sold the prized Roadster to a local car collector named Charles Selick. When Mr. Selick purchased the car in December 1975, it had covered just 37,523 miles and was repainted in traditional Mercedes-Benz silver. Throughout his decades-long ownership, Mr. Selick admired and maintained the SL, but rarely drove it, accruing fewer than 100 miles over 25 years.

After inheriting the 300 SL Roadster, his son Barry commissioned the renowned Mercedes-Benz specialist Hjeltness Restoration of Escondido, California, to perform a sympathetic, body-on restoration. This work, carried out between 2016 and 2019 at a cost of nearly $600,000, returned this important Mercedes-Benz to its original color scheme, while taking care to preserve as much originality as possible. As a result, the Roadster retains most of its nicely patinated original upholstery, except for the seats, which have been retrimmed in proper unperforated red leather.

Since joining the consignor’s magnificent sports car collection in 2023, the 300 SL has participated in the Colorado Grand, and has had its engine completely rebuilt by the respected German Mercedes-Benz specialists HK Engineering. According to an invoice on file the rebuild incorporated several sport options, including upgraded camshaft, pistons, and connecting rods, as well as an improved oil pump and HK Engineering’s ‘ready to race’ option. Now displacing 3.4 liters and producing approximately 275 horsepower, the 300 SL Roadster is reported to offer outstanding performance and increased torque, making it ideal for future event use.

Beautifully presented in all respects, this significant SL displayed just 41,845 miles at the time of cataloguing. Resplendent in its attractive original color scheme, 7500038 is accompanied by its original Karl Baisch luggage set, Becker Mexico radio, tool kit, jack, instruction manual, parts catalog, and service book, as well as its Becker manual and warranty card. Contained in the history file is a copy of the factory data card, which confirms that 7500038 retains its matching-numbers engine, together with various records dating from 1975, all the way through to recent invoices from Hjeltness Restoration and HK Engineering.

Of all the 300 SLs built, a few special examples stand apart in the minds of connoisseurs. The car presented here is among the best of the highly collectible, early-production Roadsters. Just the second example built, this factory New York show car retains its original colors, engine, and important accessories. Its history is well documented, and its presentation is superb, benefiting from nearly 50 years of single family ownership and recent restoration work undertaken by the foremost marque specialists.

For the collector in search of a truly special 300 SL, this early Roadster is worthy of serious consideration.
