2017 Bugatti Siero Seco.
From Hemmings:
"One of a kind, custom car hand made by Sean Santarsiero. The design took much inspiration from the Deco era Bugattis, such as the Type 57 and Corsica. Car is planted on a 1937 Jaguar SS100 chassis that has a automatic transmission powered by a 2.3 Murcury Capri V-6."
