1965 Ford Mustang K code

This 1965 Ford Mustang Convertible K-Code, VIN 5F08K283506, is an exceptionally rare and historically significant example of early Mustang performance. As one of the earliest documented K-Code convertibles known to exist, this car represents the top tier of Ford’s factory performance offerings during the Mustang’s first full production year. In 1965, the K-Code “Hi-Po” 289 engine stood at the peak of the lineup, featuring a solid-lifter camshaft, heavy-duty internals, upgraded suspension components, and improved drivetrain strength. Producing 271 horsepower, the K-Code package was the foundation for Ford’s early performance reputation and played a pivotal role in the development of the Shelby GT350 program. Fewer than one percent of 1965 Mustangs were factory-equipped with the K-Code engine, and convertibles were built in especially limited numbers, making this example incredibly desirable among collectors.

Adding to its significance, this Mustang is believed to be among the earliest surviving K-Code convertibles ever built. Its early production status, combined with full factory-correct components, date codes, and stampings, underscores its authenticity and rarity. The car has been restored to a condition strikingly close to concours quality, with an extensive, detailed photolog documenting the entire process. It has been driven just under three miles since the restoration was completed, preserving its flawless presentation. Every major component, from the drivetrain to the smallest supporting parts, has been restored or verified to period-correct specifications, reflecting the meticulous effort put into preserving its originality.

With its early build history, highly desirable K-Code drivetrain, and museum-quality restoration, this Mustang represents an extraordinary opportunity for collectors who value authenticity, rarity, and historic importance. It stands as a benchmark example of Ford’s early high-performance engineering and remains one of the most compelling K-Code convertibles to surface in years.
