Brand Graveyards.

Take a look at www.pontiac.com, www.oldsmobile.com, www.hummer.com, www.saab.com, and www.mercuryvehicles.com.  

Kinda sad.

Then there's http://www.suzukiauto.com/.  Not as sad, since they never really took off.

Who's next?

I nominate Misubishi and Smart, but who knows?  Maybe they have lots of money left to yet lose.
