a billion to kill a brand that costs you money is not that bad. It costs them something like 1-2 billion to bring a car from concept to production, so they'll save that money the first time they avoid having to redesign a new model.
But why kill? Sell it off...you are going to lose all that value anyways, so even if you sell Buick below market price, you still make more than if you just close the doors
