Surprising interest in the vehicle and an influx of revenue provided from the Cayenne helped Porsche decide to produce the car, and development started on a road-legal version that would be produced in small numbers at Porsche's new manufacturing facility in Leipzig. Porsche started a production run of Carrera GTs in 2004, shipping the units with an MSRP of $440,000 USD

 and a dealer invoice price of approximately $414,800 USD. In addition, the delivery charge could be as much as $5,000 USD. The first Carrera GT went on sale in the US on January 31, 2004.

Originally a production run of 1,500 cars was planned. But Porsche announced in August, 2005 that it would not continue production of the Carrera GT through 2006, citing discontinuation was due to changing airbag regulations in the US. , 1,270 GT's had been manufactured, with 604 being sold in the United States.
