By the mid-1960s, Carroll Shelby was really onto something. His hopped-up Mustangs were proving hugely popular. The Mustang’s first refresh came in 1967 with far more muscular styling, and Shelby followed suit by improving on the aggressive factory look with different tail lamps, a spoiler and lamps integrated into the car’s grille.

But it wasn’t until 1968 that Shelby finally built a GT350 Convertible for public sale (although admittedly the company toyed with prototypes earlier). With its integrated roll bar and new-for-1968 twin-snout hood scoops, the convertible was the most striking Shelby Mustang of its time. The ’68 GT350 was no slouch, either, with its 250-horsepower, 302 cubic inch V-8 capable of a sub-15 second quarter mile sprint.

Just 404 GT350 convertibles were built, with this green example being one of them. Today, it presents in almost new condition with its white side stripes, its square fog lights, and its quartet of air scoops all reminding us that it’s one of a rare breed. Inside, the GT350’s four-speed manual gear lever sprouts out of its center console, begging to be put through its paces. Under the GT350’s hood, it appears as though it just rolled out of Shelby’s then-new Ionia, Michigan, plant for its first owner.

This GT350 represents one of the rarest of its breed and has been restored to an exceptionally high standard with an extraordinary attention to detail where it matters perhaps the most—under its hood.
