Many speculated that the Buick Avista and the Opel GT will be the same car really, but with different badges. But this teaser shows a different car.

Exhaust looks different too.

So there’s a few possibilities here:

- We’re talking about different models for different markets(pretty doubtful in an increasingly global world).

- Both cars are concepts and the car that gets the most positive reactions gets built and sold globally in a badge engineering move.

- Only the Opel will be built because Chevrolet and Cadillac want to keep Buick in the mole hole.

- None of the two cars get built because GM needs to invest more in the next 30 crossovers and trucks they’ll be building.
