This example, known by the code PB1-3, is the car used for durability and weather testing during development of the Ford GT. Among its unique features: a prototype exhaust with racing headers, a pre-production transmission, and an ownership history that includes Steve Saleen.
Painted in Heritage Blue, but without the usual stripes you'd see on a GT, the PB1-3 prototype represents a unique moment in American sports car history, selling at a price that's not all that far beyond that of its production-built successors.
Even the "run of the mill" models are fairly rare, with a total of just 4,038 built over its brief run. The 550-horsepower American supercar is quick, even by today's standards, hitting 60 mph in about 3.5 seconds and a top speed limited to 205 mph.
The car is listed for $399,988 at Du Pont Registry.
