The GT1-era of the 1990s was the stuff of motorsports legend. Initially intended to be a series for modified road cars and gentlemen drivers, the class saw major manufacturers like McLaren, Mercedes-Benz, and Porsche throwing the full weight of their expertise towards factory-built race cars meant to do nothing but win the FIA GT1 Championship. No car was more dominant in that era than the CLK GTR, whose unmatched performance in the 1997 and 1998 season caused every manufacturer to effectively go back to the drawing board to begin anew.

Born from the very spirit of its most historic and significant predecessors such as the Ferrari GTO and Ford GT models of the early 1960s, the GT1 class comprised what were effectively road cars modified into race cars. Manufacturers could enter any “road car” they wished so long as at least 25 examples had been built for homologation purposes — this was Mercedes-Benz’s window. While raced against modified road cars, such as the McLaren F1, the Mercedes-Benz AMG CLK GTR was engineered from the ground up as a purpose-built race car. The main difference between the CLK road car and race car was the engine, which was a 6-Liter V-12 in the race car, and a 6.9-Liter V-12 in the road car. This massive powerplant produced over 600 hp, routed to the rear wheels through a sequential paddle shift gear box. Weighing just over 3,000 lbs., this street-legal Mercedes-Benz is capable of 0-100 mph in a little over six seconds, on to a top speed of 214 mph.

This car, serial no. 09/25, is the last of the true hypercar-race cars, with performance that rivals the latest and greatest offerings from the world’s top manufacturers. The ninth of just 25 examples built (of which 20 were coupes), this CLK GTR has led a charmed life, having had just three owners and showing shows less than 1,500 original kms since new. Fastidiously maintained, the car has been recently imported to the U.S. under the Show or Display exemption and federalized for all 50 states. It is believed that of the original 25, less than six cars are federally legal within the United States, with this being one. Offered in as-new condition, the turn-key example is ready for its next stage in greatness. Perhaps no other modern Mercedes more closely embodies the heritage of the Star and Laurel’s spirit of racing, engineering and competition; a near impossible feat to surpass since the advent of the famed 300 SL Gullwing (Est. $4,250,000 - $5,250,000).

“Unequivocally, the CLK GTR represents the most undervalued and silently underappreciated supercar of the Modern Era,” says Shelby Myers, Car Specialist, RM Sotheby’s. “Considering that it is one of the rarest high-performance production cars of its contemporaries—only 25 exist worldwide, at nearly one fourth the price of a McLaren F1, of which there are more than 60, it is only a matter of time before the model escalates to near equal market value as the $20,000,000 supercars”.

Myers continues: “Marked by what I would say is some of the most extreme yet physically attractive bodywork on a post-War sports and GT car, originally built for homologation in GT Championship racing, and in virtually flawless overall condition, I firmly believe the CLK GTR offered in our Monterey auction represents the ultimate in collector car investment and long-term value collectability”.

Final highlights for Monterey are entirely German-bred. RM Sotheby’s is also proud to be partnering with Mercedes-AMG to offer a never-raced 2017 Mercedes-AMG GT3 ‘Laureus’ in Monterey, chassis no. GT3 190-17 050, with proceeds to benefit the Laureus Sport for Good Foundation. Active in over 40 countries with support from numerous athletes on over 100 projects, the foundation aims to use the power of sports to support disadvantaged children worldwide. A one-off example of a proven victor in Mercedes-AMG’s GT racing efforts, this GT3 boasts special chrome paintwork, a performance exhaust system lacking mufflers, and exposed carbon fiber parts inside and out. Offering exceptional levels of performance and perhaps the most attractive bodywork on today’s GT3 grid, this Mercedes-AMG represents a wonderful opportunity to support a worthy cause (Est. $400,000 - $600,000, offered without reserve).

Rounding out the catalogue in spectacular fashion is one of the “giant killers”. A hugely significant piece of Porsche’s American racing history, RM Sotheby’s has added a 1957 Porsche 550A Spyder, chassis no. 550A-0116 to the Monterey lineup. By 1957, the 550 model had already found an eager customer base in North America, and chassis 0116 was delivered new to Jack McAfee of Burbank, California, who raced the car extensively on the West Coast in period. Driven and owned by some of the leading West Coast personalities through the 1990s, the 550A was subsequently comprehensively restored by marque experts in Germany. A class winner at the 2014 Amelia Island Concours d’Elegance under current ownership, the extensively documented and coveted Porsche remains highly eligible for vintage racing and international concours (Est. $4,600,000 - $5,000,000).

Held during the world-famous Pebble Beach Concours d’Elegance motoring week, RM Sotheby’s Monterey sale (24-25 August), has been the pinnacle of collector car auctions for more than 30 years, leading the field and raising the bar with its consistent, record-setting results.
