Pontiac G8.

Yeah, yeah. It was a rebadged Holden. But they were preparing to build an entirely new car probably based off the Sigma platform if sales of the G8 went well. With a wagon and a ute in the interim.

Because Pontiac died and the ‘08 Meltdown happened GM never built the Sigma successor. Instead we got the last ‘Straya built super sedan in the form of the Chevrolet SS, and the super sedan niche is completely owned by Audi and BMW now.
