 While the Darrin was designed attractively, it was also underpowered and, while a good performer overall, did not measure up to foreign vehicles such as the Nash-Healey or Triumph TR2.The Darrin's high price tag, lack of consumer confidence in Kaiser's viability and practical challenges with the car's design resulted in low sales, though sports cars at the time were generally not fast sellers.Only 435 production Darrins and six prototypes were built.
