The world's most expensive 1965 GT350 is one of only 34 R-spec cars and the first such prototype ever made. Used as an engineering test mule and a Shelby American team car, it crossed the block for a whopping $3.85 million (including fees) in 2020. And it's also the most expensive Mustang ever auctioned, having fetched about $100K more than the 1968 Ford Mustang "Bullitt" hero car.
The next five priciest GT350s ever sold are also of the R-spec variety. And they changed hands for sums between $720,000 to $990,000 in recent years. Shelby also built one prototype fitted with a Paxton supercharger, and that car found a new home for $572,000. All told, this 1965 GT350 is only the seventh most expensive rig of its kind, but it's still the proud owner of a record price tag.
So what makes this 1965 Mustang a half-million classic beyond the fact that it's rare? Well, it's an all-original gem with numbers-matching everything. Even though it's been repainted in the late 1970s, the GT350 still sports its original sheet metal and steel-reinforced fiberglass hood. The latter hides a numbers-matching 289-cubic-inch (4.7-liter) HiPo V8. The naturally aspirated mill mates with its original T10 four-speed manual.
The fastback still features the original aluminum Shelby VIN and the three Ford hidden stamps. It has a known history listed in the Shelby Registry. It comes with a ton of documentation, including original manuals and invoices. The side-exiting exhaust pipes, Cragar wheels, and Le Mans stripes are all factory options.
But wait, there's more. This GT350 still retains all of its original Shelby-installed components beyond the engine and the transmission. The list includes rear axle limiting cables, over-rider traction bars, driveshaft safety loop, aluminum-finned T-style oil pan, 3.89 rear end, and Koni shocks. The interior is also as original as they get, down to the seat belts, oil pressure gauge, and Motolita steering wheel. Needless to say, you're looking at one of the most original 1965 Mustangs out there.
The GT350 went under the hammer at Mecum's Dallas 2023 auction. It was the most expensive classic and the second-most expensive vehicle of any era, toppled only by a 2020 McLaren Speedtail. The event also saw a 1968 GT500 Convertible change hands for $220,000 and a 1966 GT350 sell for $181,500.
