It does say something when you’ve got a vehicle named “Car of the Year” (Aura), rank at the top of repeat buyers, and are somehow still underperforming. GM fucked up what on paper should be a good brand. If they did it right, I would think Saturn could use Euro sources for a vehicle lineup similar to Scion.
Buick is pointless. There is no “middle class” of cars any more. People expect so much from all cars that you can’t just add options and call it a mid-level brand. GMC is pissing in the wind, rebadging today is just paying overhead to take sales away from your own brand.
Also while Jeff’s point is well taken, I don’t think you need a brand just for performance vehicles. I don’t see what would keep Chevy from selling something like a GTP. Impala is due for a re-design anyway.
