The car: Shelby's own development prototype
Shelby American ended a six-decade drought this year by putting the GT350 badge back on a factory convertible — and this is the car that got it there. Built at Shelby's Las Vegas facility during development of the 2026 GT350 program, the prototype runs a supercharged 5.0L Coyote V8 rated at 810 hp, breathing through a Borla exhaust, under an aluminum hood, on 20-inch wheels, wearing Le Mans stripes and serialized Shelby plaques.
Why it matters
The production 2026 GT350 is capped at roughly 1,000 cars worldwide, and convertibles will be a small slice of that. A documented development prototype sits outside the numbered run entirely — for the right collector, provenance like that is the whole point. The honest counterweight: development cars live hard lives. Expect test miles (the odometer isn't published) and possibly pre-production hardware, so the usual prototype caveats apply alongside the bragging rights.
The fine print worth knowing
This is a charity sweepstakes benefiting the Shelby American Automobile Club Foundation, a 501(c)(3), and it runs March 9 through 11:59 PM PDT on September 7, 2026, with the drawing on or about September 15. Read the reserve clause carefully: the full prize — winner's choice of the car or $75,000 cash — only locks in if the Foundation collects at least $250,000 in donations during the entry period. Fall short, and the winner instead receives 25% of total proceeds. As of mid-July 2026 the operator's counter showed $193,250 raised, about 77% of the reserve with roughly seven weeks to go. Note also that the $75,000 cash option is only about 59% of the car's stated $128,000 value, so the car is the play. Donations start at $25 for 18 entries, there's a free hand-addressed mail-in route (18 entries per mailer) spelled out in the Official Rules, entry is open to those 18+ but not to Washington State residents, and the winner owes the taxes on a six-figure prize.

Why It's Special
This is the development prototype built at Shelby American's Las Vegas facility for the 2026 GT350 program — the car behind the first factory GT350 convertible in 60 years. Production 2026 GT350s are capped at roughly 1,000 cars worldwide, and a documented development prototype sits outside that count entirely.
Our value estimate
$128,000
Anchored to the operator's Official Rules, which state an approximate prize value of $128,000 — consistent with Shelby American's own $127,884 estimate cited in press coverage and with published pricing for a well-equipped supercharged 2026 GT350 convertible. No auction or resale comps exist yet: the 2026 GT350 is a brand-new model with deliveries only beginning this year, so there is no sold-price history to lean on. Two honest wrinkles: prototype provenance could add collector value or subtract it depending on documentation and pre-production hardware, and the odometer is unpublished — development test miles would move this number.
