Paul Cassell:

There is an apparent dichotomy at Cadillac and perhaps throughout GM. The engineers and True Believers are trying to build the best cars in the world but those who market them think the quality of transportation isn’t relevant to its sales potential.
 The only way to bridge this gap is to have a strong CEO decide what GM is trying to produce, automotive excellence or gaseous imagery, and then make sure the team is all on one side – whichever it may be.
 The ship of GM needs a rudder and it better get one fast. I can’t see Barra in that role.
