You know, we heard about this a day or two ago, and somehow we just didn't care enough. But it's news, and we should post it. GM dumped its stake in Isuzu. Which means no more Geo Storm. Oh, wait. We learned to drive a stick in an Isuzu, which is totally the wrong vehicle to learn to drive a stick in. Meanwhile, on a more serious note, we wonder what this means for the diesel side of GM Powertrain, as the Japanese company was a pretty substantial partner in that department.
