There is a great piece over at Minyanville that asks the question: "Is the GM turnaround Real?" The jury is still out because of UAW and their own past missteps.

“Pity the poor American car when Congress and the White House get through with it. A lightweight vehicle with a small carbon footprint using alternative energy and renewable resources to operate in a sustainable way -- when I was a kid, we called it a Schwinn.”
The piece is well worth a read.
