A rare, ultra-low-mile Carroll Shelby Signature Series Mustang is set to cross the block at the Glendale 2026 auction, offering collectors a chance to acquire one of the most extreme modern Shelby Mustangs ever produced.
Scheduled to sell Saturday, March 21, Lot V521 is a 2020 Ford Carroll Shelby Signature Series showing just 131 miles since new. It is numbered 43 of only 50 examples built and carries CSM number 20CSS0043, placing it among a highly limited run of factory-authorized, post-title Shelby performance cars.
Power comes from a supercharged 5.0-liter V-8 producing a staggering 825 horsepower. The engine is paired with an automatic transmission and backed by extensive cooling upgrades, including engine and transmission oil coolers and air-managed brake and cooling ducts integrated into the front fascia. A Borla exhaust system with custom tips handles exhaust duties, while a rear axle with a Torsen limited-slip differential and 3.73 gearing helps put the power to the pavement.
Finished in Performance Blue with white over-the-top stripes, the car presents as a modern take on classic Shelby styling. The paint has been ceramic-coated, and exterior details include aluminum front fenders with air extractors, rocker panels with integrated rocker wings, and a rear spoiler fitted with a Gurney flap. Forged one-piece monoblock polished alloy wheels are wrapped in Michelin Pilot Sport Cup 2 tires, and stopping power comes from massive Brembo brakes with six-piston front and four-piston rear calipers clamping two-piece rotors. MagneRide suspension is also equipped.
Inside, the Mustang blends track-ready performance with premium comfort. The cabin is trimmed in Katzkin leather and suede upholstery featuring a snakeskin pattern. Amenities include air conditioning, heated and ventilated seats, power windows, locks, and mirrors, as well as launch control and line lock functionality.
With production limited to just 50 units, the Carroll Shelby Signature Series represents the pinnacle of Shelby’s modern Mustang offerings, combining supercar-level horsepower with daily drivability and unmistakable Shelby pedigree. With its extremely low mileage, documented build number, and high-output configuration, this example is poised to attract serious interest when it crosses the block in Glendale.
Mecum Glendale will be selling over 2,000 collector vehicles at the State Farm Arena March 17-21. Visit their website to see all consignments and collections, buy tickets and register to bid onsite or online.
