Years Active: 1947-2011

Complex Says: We'll never forgive GM for this one. What is the purpose of buying an interesting company with a rich heritage, the world's most educated customer base, and extremely innovative engineers and designers and doing nothing more than letting its cars go without updates for over a decade and turning them into shitty Chevy clones? 

GM ruined Saab, and we're still angry about it. We're still hoping that the 9-3, pictured above, will somehow make it to market.
