A sage friend of mine explained one underlying problem with GM. Their budgeting process allocates funds to design and tooling, leaving the interior to the last. As a result the interiors of GM cars have been cheap and tawdry.
The Volt, at $40,000 is not a cheap car, but it's interior is cheap and second rate. Corporate culture or lack of it is a pernicious problem. Take a look at the current descendants of Ma Bell. They have the same insufferable attitude of their ancestor.
Merely shoveling money and green ideas into an old wine bottle will not fix the culture. And with the delicate skills of Washington bureaucrats, even less so. Thats the real problem with the Volt
