Less than a month after General Motors extended its contract to sell its Hummer brand to China’s Sichuan Tengzhong Heavy Industrial Machines Co., Ltd., the Detroit automaker has announced that it will not complete the deal..

But once we started to see families and soccer moms tanking themselves to the grocery store… we can't say this is a sad farewell.
