How Much the 2021 Ford Mustang Shelby GT500 Has Depreciated in Five Years

The 2021 Ford Mustang Shelby GT500, with its supercharged 5.2-liter V8 pumping out 760 horsepower, has followed a depreciation path that’s anything but standard. When new, the GT500 carried a base MSRP of $74,095, but its resale value today splits sharply depending on who you ask.

Edmunds pegs a top-condition example with under 64,000 miles at a trade-in value of around $47,200 and a dealer retail value of $54,900, implying a depreciation of 27% to 37%. Kelley Blue Book, however, lists the same car at over $72,000, suggesting minimal value loss.

The discrepancy stems from options like the Carbon Fiber Track Pack, which can push the GT500’s price close to or above $100,000, and low-mileage examples are often listed for over $90,000—yet lingering on the market for months without selling. The GT500’s depreciation curve is further complicated by the ultra-exclusive Shelby GT500KR, a limited-run variant celebrating Shelby American’s 60th anniversary.

With only 180 units built for North America (60 in 2021) and 45 for overseas, the GT500KR’s value has skyrocketed. Classic.com data shows 2021 GT500KR models trading between $154,000 and $330,000, with an average transaction price around $202,000—far above its original $127,895 MSRP.

The GT500KR’s supercharged 5.2-liter V8 cranks out 900 horsepower, making it a supercar-beating muscle car, but its scarcity is the real value driver. Meanwhile, the standard GT500’s depreciation remains softer than most Mustangs, including the electric Mustang Mach-E, though its fate hinges on buyer demand and option pricing.

For now, the GT500’s resale story is a tale of extremes: a base model that’s holding value better than expected, and a limited-edition KR that’s become a modern classic overnight.
