2008 Ford Mustang Shelby GT500KR For Sale: Low-Mileage King of the Road with More Power Than a New Dark Horse

A highly desirable and ultra-low-mileage 2008 Ford Mustang Shelby GT500KR (King of the Road) is currently on auction at Cars & Bids, showing just 6,200 miles from new. This fifth-generation Mustang, which pays tribute to the original 1968 model, is one of only 1,011 examples produced for the 2008 model year. With its factory-upgraded 5.4-liter supercharged V8 pushing 540 horsepower and 510 lb-ft of torque, this GT500KR delivers significantly more power than a new 2026 Mustang Dark Horse (500 hp / 418 lb-ft), making it a powerful and exclusive collectible.

GT500KR: Exclusivity and Performance Heritage

The GT500KR package transforms the standard Mustang into a collector-grade machine with enhanced power and unique styling.

Production Rarity: Only 1,011 examples of the GT500KR were produced for the 2008 model year.
Original Cost: The car’s total new price was $77,345 ($43,780 base GT500 + $33,565 KR Package).
Engine Output: The 5.4-liter supercharged V8, in standard form making 500 hp, is bumped to 540 hp and 510 lb-ft of torque with the KR package upgrades.
Dark Horse Comparison: The KR’s 540 horsepower is notably more than the 500 horsepower produced by the top-tier naturally aspirated 2026 Mustang Dark Horse.

KR Package Upgrades and Condition

The car on auction boasts numerous upgrades and remains in remarkably preserved condition.

Performance Upgrades: The KR Package includes a cold air intake kit, a Pro-Cal performance calibration, a special H-Pipe exhaust, and performance mufflers.
Handling: Suspension features revised front/rear springs, stiffer front struts and rear shocks, and a strut tower brace.
Exterior: Finished in Silver Clearcoat Metallic with the Shelby Racing Stripe Kit. It features carbon fiber for the hood (with functional intakes/extractors), front splitter, and mirror skull caps.
Interior: The black leather interior is beautifully preserved, featuring Carroll Shelby signature headrests and a Shaker 500 sound system.

Market Value and Auction Outlook

Recent comparable sales suggest this low-mileage example is likely to sell for a premium over the standard GT500.

Current Auction Status: The current high bid is $35,000, with the auction running until November 5.
Comparable Sales: A 56-mile 2008 GT500KR sold for $62,000 last month on Bring a Trailer, and another 4,900-mile example sold for $47,001 in September.
Estimated Value: Given its rarity (1,011 units) and low mileage (6,200 miles), the auction suggests this GT500KR is a good deal for anything under $50,000, though its value in mint condition can reach significantly higher figures at peak auction times.
Flaws: Known flaws include original 2008 date-coded tires, front lip chips, scuffs on the driver’s door sill, and rust on some underbody components.

Final Thoughts

This 2008 Mustang Shelby GT500KR is more than just a powerful car; it is a meticulously preserved piece of American muscle car history and a powerful tribute to Carroll Shelby’s “King of the Road” legacy. Its blend of throwback styling, raw supercharged V8 power, and its superior performance figures over the new Dark Horse make it a highly desirable collectible. The auction presents a compelling opportunity for enthusiasts to own a rare S197 that is entering true collector status.
