1. Pontiac
Once synonymous with American muscle, Pontiac thrilled drivers with legends like the Firebird and GTO. Despite a passionate fanbase, the brand could not survive General Motors’ massive restructuring during the 2008 financial crisis. By 2010, Pontiac’s engines fell silent, but not before leaving a legacy of performance, attitude, and style. The brand’s final years reminded enthusiasts everywhere how a carmaker can go out with a roar, not a whimper. [Source]
