One-Owner, All Matching Numbers, First-Time Public Offering!
Unbelievably rare, fully documented, and offered to the public for the very first time. This one-owner California Boss 429 is entirely matching numbers, factory-original, and officially listed in the Boss 429 Registry.
Offered here is an extraordinary 1969 Ford Mustang Boss 429 — an untouched California original, meticulously maintained, and historically significant. This car has never been publicly offered before. Purchased directly from its original owner in Southern California earlier this summer, it has remained in the same hands from new until now. Its full 56-year life has been spent in Southern California, making it an unbroken black plate California car from day one.
Special-ordered and delivered through Culver City Ford, this Boss 429 is a documented one-of-one in its delivery history — the only Royal Maroon Boss 429 ever sold through that dealership. Accompanied by an exceptional archive of original documentation, this car remains a pristine example of Ford’s legendary homologation program.
The Boss 429 was Ford’s bold response to NASCAR’s horsepower wars in the late 1960s. To qualify the massive 429ci semi-hemi V8 for competition, Ford had to produce at least 500 street cars — giving birth to one of the most exotic muscle cars ever made.
Because the engine could not fit a standard Mustang assembly line, Kar Kraft hand-built each chassis with relocated front shock towers, reinforced frame rails, and suspension modifications, making every Boss 429 a true hand-crafted homologation special.

Original features and options:
This Boss 429 is the ultimate combination of rarity, originality, and provenance. With one-owner California history, first-time availability, Boss 429 Registry listing, and complete documentation, it represents far more than a muscle car — it is a once-in-a-lifetime collector’s acquisition.
Few 1969 Boss 429s ever come to market, and almost none remain tied to their original owner. This combination of provenance, exclusivity, and factory originality makes this car a true blue-chip investment, destined to anchor a world-class collection and appreciate in both historical and financial significance.
A true once-in-a-lifetime Boss 429 — original, factory-unique, Kar Kraft-engineered, and collector-grade scarce. Opportunities like this do not repeat.
