Most race cars from the 1960s survived by being repaired, modified, crashed, rebuilt, and sent straight back onto the track. Finding one that escaped decades of competition with its original structure largely intact is as rare as hen’s teeth.
That is what makes this 1965 Shelby GT350 R-Model, chassis SFM5R534, such an unusual piece of Mustang history. Mecum describes it as perhaps the most original, properly preserved factory GT350 R-Model in existence, and it is now preparing to cross the auction block.
Only 36 factory-built GT350 R-Models were produced, making any genuine example significant. This particular car reportedly retains 100 percent of its original sheet metal, a remarkable claim for a Mustang specifically constructed to spend its life racing.
The Shelby is scheduled to be offered at Mecum’s Kissimmee 2027 auction on Friday, January 15. No auction estimate has been announced, although the combination of rarity, provenance, and originality should make it one of the more interesting Shelby sales to watch.
Shelby Turned The GT350 Into A Serious Race Car
The standard 1965 Shelby GT350 was already a substantially more focused Mustang than the regular Ford model. The R-Model pushed that transformation much further, with Shelby American developing it specifically for SCCA B-Production competition.
That connection puts the little Mustang in impressive company. Shelby American was simultaneously responsible for machines including the Cobra and Daytona Coupe, while also playing a central role in Ford’s GT40 racing program.
Under the hood of SFM5R534 sits a 289-cubic-inch V8 connected to a four-speed manual transmission. The car is finished in the quintessential Shelby combination of Wimbledon White with blue stripes, while its stripped-down black cabin reflects its competition purpose.
The GT350 R-Model wasn’t created simply to look like a racing Mustang. It was built to compete, and its success helped establish the Mustang’s performance credentials at a point when Ford’s pony car was still a relatively new arrival.
This One Still Has Its Original Sheet Metal
SFM5R534’s greatest distinction may be what hasn’t been replaced. According to Mecum, the car retains all of its original sheet metal despite its history as a competition machine.
Noted Shelby authority Bob Perkins has described it as the only example he has examined with 100 percent original sheet metal. Considering the abuse racing cars typically endured, surviving without the replacement panels commonly fitted after crashes or damage makes this GT350 R particularly noteworthy.
Its history is also extensively documented. Mecum says the Shelby comes with original paperwork connecting it to its first owner, period racing photographs, and a known history stretching from its construction at Shelby American through to the present.
The car was extensively photographed before its cosmetic restoration, when it still wore original paint and factory markings. Its restoration was also documented, helping preserve details that have subsequently made SFM5R534 useful as a reference when authenticating and restoring other GT350 R-Models.
It’s Already A Reference Point For Other GT350 Rs
That level of preservation has given the car significance beyond its own provenance. Mecum says the car has been used over the years as an important reference example for other factory R-Models.
It has also received Concours Gold Certification at the Muscle Car and Corvette Nationals. While the Shelby has undergone cosmetic restoration, Mecum emphasizes that it otherwise remains remarkably close to its original configuration as delivered by Shelby American.
Vintage racing cars can look spectacular when restored, but an extensively preserved car can reveal construction details, factory techniques, and competition modifications that might otherwise have disappeared decades ago.
It Heads To Kissimmee In January
Mecum will offer the GT350 R-Model during its Kissimmee auction on January 15, 2027. The auction house hasn’t published an estimate, so exactly where bidding will land remains to be seen.
There will certainly be no shortage of historical significance crossing the block. With only 36 factory R-Models built and this example retaining its original sheet metal alongside extensive documentation, SFM5R534 represents an unusually intact survivor from one of the most important chapters in Shelby and Mustang racing history.
