Shelby GT500

The Shelby GT500 arrived in 1967 as the top-of-the-line Mustang from Carroll Shelby's workshop. It packed Ford's big-block 428-cubic-inch Police Interceptor V8, offering more power and comfort than the small-block GT350. With aggressive fiberglass bodywork and an upgraded interior, it was marketed as a high-performance grand tourer for the discerning driver.

Collectors prize the GT500 for its direct link to Carroll Shelby and its status as the ultimate 1960s muscle Mustang. Its blend of big-block power, iconic styling, and limited production makes it a blue-chip collectible. The 1967 models are often seen as the purest, while the 1968 GT500KR (King of the Road) with its 428 Cobra Jet engine is one of the most desirable variants. Documentation from the Shelby American Automobile Club (SAAC) is crucial for verifying authenticity and value.

The market for genuine GT500s is mature and commands high prices, with an average transaction value of $189,118. Condition, originality, and documentation cause significant price swings. While driver-quality cars can be found, concours-level examples and rare models like the KR or convertibles consistently fetch premium prices at auction.

Prices range from $73,000 for project cars to $2,200,000 for the rarest, most significant examples.
