Classic Mustangs are no strangers to custom builds, but few transformations are as dramatic as this one. What began life as a 1966 Ford Mustang coupe has been converted into a full-length limousine measuring approximately 21 feet from bumper to bumper.
The unusual creation recently found a new owner after selling on Bring a Trailer for $40,000. While some enthusiasts may see it as an automotive curiosity, others may view it as one of the most unconventional Mustang conversions ever built.
According to the auction listing, the limousine conversion was completed sometime before 2000 and remained with a collector for roughly two decades before changing hands. The result combines classic pony car styling with limousine features that would have seemed unimaginable when the Mustang first rolled off the assembly line.
Love it or hate it, there’s no denying the craftsmanship involved. Stretching a unibody sports coupe into a functioning limousine requires far more engineering than simply adding extra sheet metal between the wheels.
Turning A Pony Car Into A Limousine
Unlike traditional body-on-frame vehicles, the first-generation Mustang uses a unibody construction, meaning the body itself provides much of the car’s structural strength. Extending the wheelbase requires substantial fabrication to maintain rigidity while accommodating the additional length.
This build features a custom center section complete with a fabricated B-pillar and reverse-opening rear doors. The rear-hinged entry gives passengers easier access to the extended cabin while adding a classic limousine touch.
The exterior was refinished in Tahoe Turquoise around eight years ago and features a white vinyl roof stretching the entire length of the car. Additional custom touches include a GT-style rear valance with dual exhaust outlets, a boomerang-style antenna, and a pop-up sunroof positioned above the rear passenger compartment.
Modern upgrades have also been incorporated, including 17-inch Torq Thrust-style wheels, power-assisted front disc brakes, rear air shocks, and power steering to help manage the limousine’s increased size.
Classic V8 Power Remains Under The Hood
Despite the extensive body modifications, the drivetrain stays relatively faithful to the Mustang’s era. Power comes from a 289-cubic-inch V8 paired with a C4 three-speed automatic transmission driving an 8-inch rear axle.
According to the seller, the engine was rebuilt roughly eight years ago. Recent maintenance included a new carburetor, ignition components, spark plugs, wiring, battery, fluids, and fuel sending unit, helping prepare the car for its next owner.
An aluminum radiator and Monte Carlo bar have also been installed beneath the hood. The odometer shows approximately 95,000 miles, with only around 200 added during the seller’s ownership.
While the powertrain remains relatively straightforward by modern standards, it provides an authentic period-correct soundtrack that suits the car’s vintage character.
A Limousine Cabin Unlike Any Other
Inside, the Mustang bears little resemblance to the compact coupe it once was. The stretched passenger compartment includes two additional rows of seating behind a custom divider separating the rear cabin from the driver.
Rear passengers benefit from their own dedicated air conditioning system, while the front retains bucket seats trimmed in two-tone Pony upholstery. A wood-rim steering wheel, white-faced gauges, tilt steering column, and Bluetooth-compatible retro-style audio system blend classic styling with modern convenience.
The car also includes rear speakers, a custom console, and several comfort upgrades designed to make it suitable for chauffeured cruising rather than spirited backroad driving. The only known issue noted in the auction listing is an inoperative fuel gauge.
Whether viewed as an impressive piece of coachbuilding or a bold departure from Mustang tradition, this stretched 1966 Ford certainly stands apart from the thousands of restored classics seen at car shows every year. At $40,000, its new owner now possesses one of the most unusual first-generation Mustangs likely to ever appear on the road.
