Ed is as much what GM needs to compete in the auto business as I am what Penske needs to compete in NASCAR.
Until they go get a world class CEO, who understands cars, who knows cars, who knows customers, wears designer clothes, who is fashion and fad aware, they will remain a third rate auto manufacturer ran by old men wearing K-Mart suits without a clue what it means to be hip.
Car business is about being cool and trendy. If they think all the customers want is a reliable safe car to go from one place to another, they will keep manufacturing Cavaliers and Cobalts and Impalas that do all that. However it is obvious, THAT IS NOT ENOUGH.. People want more.
