This early-production 2005 Ford GT is powered by a supercharged 5.4-liter twin-turbocharged V8 engine.

It was modified in 2005 by Jason Heffner from Sarasota, FL, and was assigned serial number 1.

It features billet aluminum control arms field-installed by Ford after the initial sale.

This GT also features the Ford Performance exhaust and shorty headers.
