This show car, a 911 Turbo with an air-cooled engine, is painted in the carmaker’s Golden Yellow Metallic, the same color as its 2018 911 Turbo S Exclusive Series. This car also features black wheels with gold highlights, while seats and interior trim also are finished in black with Golden Yellow details.

Exterior features include the air intakes of the 993 Turbo S that were also available as an option for the regular 911 Turbo in 1998. Porsche stopped production of the 993 about 20 years ago.
