1983 PPG Daytona Turbo Z Pace Car, one of one. This was built before there were any production Daytonas--none of the body panels match the production models. It has no headlights, no turn signals and no license-plate well. And, boy, it is loud.
The owner also has '89 Shelby CSX-VNT #1 of 500, from the Carroll Shelby collection.
