There’s something special about a first-generation Ford Mustang. From the clean early lines of the ’64½ cars to the aggressive stance of the ’71–’73 models, these cars defined the pony car era and still turn heads today.

It’s not just the big-ticket items that make a Mustang stand out - it’s the details.

What if Carroll Hall Shelby continued his productive and astonishing collaboration with the Ford Motor Company well into the 1980s and '90s, and Lee Iacocca asked Old Shel' to envision, design, and build a Fox-bodied Shelby Mustang? The Foxy Shelby would need to have the quintessential Shelby design and performance that was the stunning success of the 1965-1970 Shelby Mustang GT350 and GT500 variants that tore up the racing tarmac and dealer showrooms of the latter 1960s and helped to vanish the contents of many a gear heads' savings accounts from the past to the ever present. Hmmm...

World famous custom car designer and builder Chip Foose postulates this interesting what if in a YouTube video, sponsored by Hagerty Classic Car Insurance. Stay tuned, motor mavens of the midway and gear heads of all generations! The 5.0 Shelby is on its way. We wish...

The term "restomod" can be interpreted a number of different ways. To many enthusiasts, a restomod is simply a restored car with a few off-the-shelf aftermarket upgrades installed. However, Revology sees their 1969 Boss 429 Mustang as a vehicle that pushes the limits of this term. Tom Scarpello, founder and CEO of Revology, explains, "Technically it's a restomod, but in reality, it's not... it's so far from just a collection of parts bolted to an existing car." Revology's vision for a modernized Boss 429 resulted in a car with some impressive engineering under its classic 1960s-era surface.

Thanks to a bit of some smart horse trading, a couple of vintage Mustangs are being kept all in the family. Seven years ago, Westminster, California resident, Rudy Doles, and his family were attending his Uncle Vic's funeral. Rudy noticed that Vic's 1967 Mustang convertible wasn't in his garage. Rudy asked a cousin attending the funeral where the drop top pony car might have wandered off to.

Every year at the SEMA Show, we make a point of checking out the newest restomod build from Ringbrothers, and even after 20 years, we have yet to be disappointed. These brothers from Wisconsin consistently produce some of the coolest resto-modded classic cars in the industry, and their project for 2025 was no exception. This 1969 Mustang Mach 1, known as Kingpin, features a stretched and widened body, independent suspension, tons of custom one-of-a-kind parts, and an 800hp Coyote V8.

Some cars are engineered. A rare few are conjured. In 1967, when Ford widened the Mustang just enough to swallow its muscular 390/320-horsepower big-block, the move cracked open a door. Carroll Shelby, eternal hot-rod alchemist, kicked the slightly ajar door off its hinges. The GT500 arrived as the natural evolution of performance, its Police Interceptor 428 already massaged to 355 horsepower. The public devoured it, outselling the GT350 by nearly double. But beneath Shelby’s trademark Texas grin, another idea was forming - larger, louder, and impossibly ambitious.

And as in so many moments of automotive destiny, it took only a spark to ignite a legend.
