If anyone could have pulled this off, it was Roger Penske....
He rescued Detroit Diesel from GM several years ago, when it looked like GM was just going to let it "wither on the vine".
GM, whether it's their management group or their design and engineering departments, can't
seem to get their heads out of their asses long enough to allow oxygen back into their brains.

You'd almost think the company was run by DUmmies....
(Oh, wait. IT IS!)
Thank GOD I own a Ford....
