The Ford Mustang isn’t just a car; it’s a cultural icon. With decades of production, millions of units sold, and enough trim levels to confuse a seasoned gearhead, it’s no surprise that Ford’s pony car has had its share of experimental ideas. Some of these Mustangs became legends. Others? They quietly vanished into footnote status: rare, misunderstood, or just too ahead of their time to succeed.
Since its April 1964 debut as a 1965 model year car, Ford has offered plenty of special Mustangs, but some are more special than others. In fact, some are so special that only dyed-in-the-wool Mustang enthusiasts know about them. From all-wheel-drive prototypes to Italian-designed one-offs, these are the rare Mustangs that prove just how bold (and occasionally bizarre) Ford could be when it came to reimagining its most beloved nameplate.
What Makes a Mustang Worth Remembering

To create this list, we dug through decades of Mustang history, paying special attention to the obscure, the experimental, and the underappreciated. We pulled information from trusted automotive sources, including MotorTrend, Road & Track, Ford Authority, Car and Driver, and Hemmings, along with input from dedicated Mustang fan communities.
Our goal wasn’t just to showcase rare Mustangs by production numbers but to highlight the bold ideas that made these cars stand out, whether through design, engineering, or sheer gutsiness. Some were built for racing, others for show, and a few were just the result of brilliant (or bizarre) experimentation.
2006 Ford Mustang Giugiaro

MotorTrend says that when Fabrizio Giugiaro, son of legendary auto designer Giorgetto Giugiaro, first saw the new retro-styled S197 Mustang in the mid-2000s, he couldn’t help himself and had to design a concept version for Ford. That resulted in the gorgeous car you see here, a Mustang that was inspired by European sports cars, including the doors that open upwards, like on a Lambo.
Under the hood, it had a supercharged 4.6-liter V8 pumping out 500 hp, so it wasn’t all show and no go, either. Despite the concept offering a fresh take on the Mustang’s design, Ford never pursued it beyond the concept stage.
2000 Ford Mustang SVT Cobra R

Ford introduced the first SVT Cobra model in 1993, and by 2000, it had already seen several versions. Car & Driver reports that, in 2000, the Mustang SVT Cobra R returned for a limited production run of just 300 cars. There was no regular Cobra this year, so the Cobra R was the only high-performance Mustang available.
It was packing a 5.4-liter DOHC V8 rated at 385 hp
1970 Mustang Grabber

Old-school Ford enthusiasts have probably heard of the Ford Maverick Grabber, but we bet not as many have heard of the more obscure Mustang Grabber. MotorTrend tells us the Mustang Grabber was a promotional special appearance package built around loud Grabber paint colors and sporty graphics.
It was primarily an appearance and trim bundle rather than a separate model, and it did not automatically include a specific engine, so buyers could pair it with different powertrains depending on how they ordered the car.
1965 Ford Mustang Ferguson AWD

Hemmings reports that Harry Ferguson Research Ltd. in the United Kingdom developed the Ferguson Formula all-wheel-drive system and applied it to a small batch of 1965 Mustang evaluation cars. The goal was to prove the concept in a normal road car, and the converted Mustang was later sent back to the United States for wider testing.
The Ferguson Formula setup was rear biased, typically sending about 63% of torque to the rear wheels and 37% to the front. Testing impressed engineers, but Ford ultimately decided the added cost and complexity were too difficult to justify for series production at the time.
1969 Ford Mustang BOSS 429 LID

The Boss 429 was created so Ford could homologate its 429 V8 for NASCAR competition. Fitting the massive engine required extensive modifications, and the result was a Mustang built in very low numbers that has become one of the most coveted factory Mustangs ever produced.
Why These Rare Mustangs Still Matter

The Mustang has always been more than just a car; it’s a canvas for innovation. While the GTs, Cobras, and Bosses earned their spotlight, these rare and often forgotten Mustangs remind us just how far Ford was willing to go to push the envelope.
From Italian styling houses to AWD experiments and mid-engine monsters, these Mustangs prove that even within a well-known nameplate, there’s always room for the unexpected. Whether you’re a die-hard fan or just love a good car story, these hidden gems show that Mustang history is full of surprises—and some of the best chapters are the ones most people never read.
