The Most Expensive Chevrolet Ever Sold Isn’t A COPO Camaro Or An L88
A 1969 Yenko Camaro prototype sold for $1,815,000 at Mecum Kissimmee in January 2026, the most money any Camaro has ever brought at auction. The best 1967 L88 Corvette managed $3,850,000, and that was back in 2014.
Both figures now look like pocket change. A classic Chevrolet crossed the block at RM Sotheby’s Monterey sale on August 15, 2026, and cleared the previous brand record of $7,705,000 by more than double. Only five examples were ever built for a single purpose – which was to go racing.
What Chevrolet’s Most Expensive Cars Were Worth So Far
The most expensive Camaro ever sold is a 1969 Yenko prototype that brought $1,815,000 at Mecum Kissimmee in January 2026, taking the title from a 1969 ZL1 that made $1,094,000 at Barrett-Jackson in 2020. A second ZL1 came close in May 2026, selling for $1,430,000 at Mecum Indy.
The L88 tier sits higher, but it has stalled. A red-on-red 1967 L88 set the Corvette record at $3,850,000 in 2014, came back a decade later for $3,200,000, then went unsold three times in 2025.
That 2014 record finally fell in early 2025, when the 1957 Corvette SS racer sold for $7,705,000 at RM Sotheby’s Miami. Race cars, not option codes, now set the ceiling for the brand. The SS was a one-off factory prototype that never raced a full season, and it still cleared the best L88 by nearly $4,000,000.
RM Sotheby’s expected the Monterey car to land between $11,000,000 and $13,000,000, which would have beaten that mark on its own. Bidding cleared the top of the estimate before the hammer fell, and then kept going.
Chevrolet’s best Camaro result would not cover a tenth of what this car brought, and the previous brand record would not cover half of it. Monterey Car Week 2026 finished at an all-time high of roughly $748 million in total sales, and this was among the largest single results of the week.
Chassis 003: The $18,705,000 Corvette Grand Sport Built Behind GM’s Back
The car is a 1963 Chevrolet Corvette Grand Sport, chassis 003, offered as Lot 341 with VIN 30837X100003. It hammered at $17,000,000, and commissions brought the final price to $18,705,000. Five Grand Sports were built in total, three of them as coupes, and 003 was the first coupe completed.
That figure beat the top of RM Sotheby’s estimate by $5,705,000. It also made a car that Chevrolet officially never built worth more than every documented L88, ZL1, and COPO Camaro sold at auction combined.
Chevrolet’s answer to Carroll Shelby’s Cobra in 1963 was the Z06 package, and it did not work. The Cobra was lighter, and weight was the Corvette’s core weakness. Zora Arkus-Duntov concluded that trimming a production car would never close the gap.
A production 1963 Corvette weighed around 3,200 lbs while the Grand Sport came in near 1,900 lbs, which is like removing the baby elephant from the passenger seat. Underneath sat a frame built from seamless thin-wall steel tubing, with hand-formed aluminum bracing in the cockpit.
The body was a single-piece hand-laid fiberglass shell with thinner panels, fixed headlamps, and Plexiglas side and rear windows. Girling disc brakes with aluminum calipers, an aluminum differential housing, and Halibrand magnesium knock-off wheels finished the package.
Aluminum replaced steel in the door hardware, hood hinges, steering components, and even the wiper mechanism, while magnesium was used for the carburetor adapters. Hundreds of parts on the car had no equivalent on a showroom Sting Ray.
GM chairman Frederic Donner ordered the program killed once word of the Sebring testing leaked, since the company had officially quit racing years earlier. Arkus-Duntov kept developing the five cars through unofficial channels, with quiet cover from Chevrolet general manager Bunkie Knudsen.
The first cars ran iron-block 327-cubic-inch V8s rather than anything exotic. Arkus-Duntov wanted reliability while his engineers gathered data, and the bigger engines could wait.
The Grand Sports Beat The Cobras In Nassau, 1963
Dick Doane ran chassis 003 in eight SCCA events between July and November 1963, taking class wins at Wilmot and Greenwood. His dealership in Dundee, Illinois advertised itself as the world’s best known Corvette dealer. Because the car fell outside production rules, it competed in C-Modified.
At the Road America 500 the Grand Sport led outright for 93 laps before the engine failed. Doane solved a heat problem during that same race by punching eight cooling holes into the rear valance below the taillights. Every other Grand Sport copied the fix.
Chevrolet Engineering rebuilt 003, 004, and 005 ahead of the Bahamas Speed Week in December 1963, and John Mecom Jr.’s team ran them. Carroll Shelby was photographed studying the cars in the paddock. They now carried all-aluminum 377-cubic-inch V8s with four Weber 58 DCOE carburetors on a cross-ram intake, plus wider Halibrands and flared fenders.
Jim Hall qualified 003 third overall for the Tourist Trophy, then all three cars cooked their differentials in the race. Engineers built an external oil cooler into the decklid overnight, and the problem never returned.
Augie Pabst took 003 to fourth overall in the Governor’s Cup. John Cannon followed with second in class and eighth overall in the Nassau Trophy, while Dick Thompson won the class outright in 005.
The Grand Sports outran Shelby’s Cobras down Nassau’s long straights and collected the nickname Snake Eaters. They also reached international competition months before the Cobra Daytona Coupe turned a wheel in anger.
A.J. Foyt Started 62nd And Passed 50 Cars On The Opening Lap
Mecom entered chassis 003 as car number 2 at the 1964 Sebring 12 Hours, now running an iron-block 377 with four-carburetor induction. A.J. Foyt shared the drive with John Cannon.
Mechanical trouble in qualifying left the car 62nd on a 66-car grid and Foyt passed close to 50 cars on the opening lap. The Corvette climbed as high as eighth overall before a worn axle spline let a wheel work loose. An unrelated crash then blocked the pit exit while the crew worked. Cannon and Foyt recovered to finish 23rd overall and second in class.
That same race marked the competition debut of Shelby’s Cobra Daytona Coupe, opening a rivalry that would run for decades. Jack Saunders drove 003 to second in class at the Houston SCCA Regionals in October 1964, then took it back to Nassau as car 00 for third in class in the Tourist Trophy.
Alan Sevadjian bought the car in January 1965 at the age of 19, with Delmo Johnson handling preparation and Arkus-Duntov quietly supplying a 427-cubic-inch big block. Ridgeway Racing entered it as car 1 at the 1965 Sebring 12 Hours for Johnson, Ed Sevadjian, and Dave Morgan, and it finished third in class. Johnson later described driving it as being “like a dragster,” and said it was the only car he ever drove that would lift its front wheels in every gear. Ed Sevadjian closed out the front-line career with a class win at the Hammond National in May 1965.
Why $18 Million Wasn’t An Overpay
Chassis 003 escaped the crashes that consumed most front-line racers of its era. Three long-term custodians looked after it across roughly 50 years, and the current owner has held it since 2003. Its tubular chassis, lightweight body, dashboard, and seats are all believed to be original.
Terry Scarborough Racing in Sonoma spent more than four years and over 4,000 labor hours on the restoration, at a cost approaching $1,000,000. The engine fitted now is a fresh all-aluminum 377 running original Webers on an original cross-ram, rated at more than 600 hp and 600 lb-ft. That figure is restoration spec rather than a 1963 factory number.
The paperwork is equally strong, with a place in the Bloomington Gold Hall of Fame in 1997 among the first 33 cars honored and an NCRS Special Interest Award in 2002. The car still gets used, appearing at the Goodwood Festival of Speed in 2010 and returning to Laguna Seca in 2023 for Corvette’s 70th anniversary.
Rarity alone does not set the price. Five Grand Sports exist against six Cobra Daytona Coupes, yet CSX2300 sold for $42,905,000 the night before at Gooding Christie’s to become the most expensive American car ever auctioned. With the 1935 Duesenberg SSJ selling for $22 million in 2018, 1963 Corvette Grand Sport Chassis 003 stands in the top three.
The Grand Sport Legacy Carried On The Road
Chevrolet revived the Grand Sport name in 1996 for the final C4, again in 2010 on the C6, and once more in 2017 on the C7, each time wrapping a standard V8 in wide-body Z06 hardware.
The 2027 Corvette Grand Sport was previewed at Sebring in March 2026, on the circuit where Foyt drove 003. It pairs the Z06 body with the new 6.7-liter LS6 V8 for 535 hp and 520 lb-ft, priced from $88,495, while the Grand Sport X adds a 186-hp front electric motor for 721 hp and all-wheel drive. Both now sit between the Stingray and the Z06, in the slot the original never got to fill.
