Collector Car News to Start Your DayModern Car CollectorEve NowellThu, September 17, 2026 at 11:00 AM UTCAdd us on GoogleWednesday on Modern Car Collector kept circling back to one question from different directions: does a car's price come from what happened to it, or from what can be proven? A 1991 Acura NSX and a 1940 Harley-Davidson Knucklehead EL both leaned on clean, documented, low-mile histories. "Little Red" added another line to its provenance file without ever touching an auction block. And on Bring a Trailer, a factory-built Aston Martin continuation and a Ferrari re-creation carrying a disputed chassis tag sold for the exact same price, proof that a good story can price in nearly as much as a clean one right now. In between, a supercharged Bel Air, a hybrid Corvette still writing its own collector case, and a preview of the week's five biggest sales rounded out the day. Here's everything we published on September 16, in order, so you can catch up on anything you missed.For Sale: This Modified 1991 Acura NSX Is Heading to the Saratoga Motorcar AuctionA modified 1991 Acura NSX heading to the Saratoga Motorcar Auction pairs a Comptech supercharger and carbon fiber air box with Brembo brakes, OZ Racing wheels, and a fully adjustable suspension. The consignor lists just 30,567 miles under single ownership, exactly the kind of clean, sorted, low-mile example that is driving renewed collector interest in Honda's original supercar.For Sale from the Rick Yerick Collection Auction: A 1940 Harley-Davidson Knucklehead EL Worth Getting Excited AboutOffered as Lot #101 by Premier Assets LLC through Proxibid, this EL Knucklehead carries a clean Ohio title and a genuine 61-cubic-inch V-twin that the seller says cranks over. Correct chevron fender trim, laced wheels, and 98,522 honest miles point to a bike preserved rather than reinvented, with bidding closing September 17.Final Days to Enter: Win a 2026 Corvette ZR1 and Get Double Entries with MCC's Sweepstakes LinkThe Chip Miller Amyloidosis Foundation's sweepstakes for a 1,064-horsepower 2026 Corvette ZR1 with the ZTK Performance Package enters its final days, and MCC readers can grab bonus entries through our link before the September 27 deadline. Every donation also funds amyloidosis research, the disease that took Corvettes at Carlisle co-founder Chip Miller in 2004.For Sale at Henderson Auctions: A Fuel-Injected 1957 Chevrolet Bel Air Convertible Worth Falling ForAdvertisementAdvertisementFinished in Matador Red with the desirable 283-cubic-inch Rochester Ramjet fuel-injected V8 — the "Fuelie" — paired to a 3-speed manual, this tri-five Bel Air convertible is bid to $10,250 and climbing at Henderson Auctions' Collector Motor Series sale. It crosses the block September 26 at Barber Motorsports Park in Birmingham, Alabama.Collector Car Market Brief: A Continuation, a Recreation, and the $1,000,999 They ShareBring a Trailer's last 24 hours produced the week's strangest data point: a factory-built Aston Martin DB4 GT Continuation and a Ferrari 330 GTO re-creation carrying a disputed, resurrected chassis tag sold for the identical price of $1,000,999. Elsewhere, a 1969 Miura once owned by F1 driver René Arnoux headlines RM Sotheby's Zurich sale, and a low-mile Buick GNX bid to $180,000 without clearing reserve — real resistance even on a genuine muscle-era icon.Is the 2026 Chevrolet Corvette ZR1X a Future Collector Car?The 1,250-horsepower ZR1X pairs a twin-turbo, flat-plane-crank V8 with an electric front axle for the first hybrid all-wheel-drive Corvette ever built, and it has already edged the Ford Mustang GTD's Nurburgring lap record. Whether that engineering leap becomes collector-grade depends on documentation and scarcity Chevrolet hasn't defined yet — no hard production cap exists, and real collector status usually takes a decade to reveal itself.A 507-Kilometer Mercedes-AMG ONE Is Heading to Auction. Here's What It's Actually Worth.A single-owner, 507-kilometer 2024 Mercedes-AMG ONE — the road car built around Mercedes-AMG's Formula 1 hybrid power unit — heads to RM Sotheby's Zurich sale on September 26 with a conservative CHF 2.3–2.5 million estimate. Full documentation and low mileage sit below the model's recent comparable results, making this hammer price a real test of where hybrid hypercar values have settled.Collector Car Auctions To Watch: September 17–21, 2026AdvertisementAdvertisementFive live sales spread across Indiana, New York, Colorado, Pennsylvania and the Sussex countryside cross the block September 17–21, from a matching-numbers 1955 Mercedes-Benz 300SL Gullwing at Saratoga to a one-of-70 Aston Martin DB4 SS Vantage Convertible headlining Bonhams' Goodwood Revival sale. VanDerBrink's 300-vehicle Born Family Estate Collection tests the market's other end: unrestored project metal going out at whatever the room will pay.Today in Collector Car History: 'Little Red' Met Its Only Surviving Shelby GT500 Sibling for the First Time, 5 Years Ago TodayFive years ago today, Barrett-Jackson placed "Little Red" — the only Shelby GT500 notchback coupe ever built — alongside the only surviving 1967 GT500 convertible for the two cars' first public reunion at its inaugural Houston Auction. Neither car crossed the block, but the display added another documented public appearance to the chain of custody that is the entire basis of a one-off prototype's value.That's the full slate for September 16.
