The problem with many folks in the US auto industry is that they actually don't know diddly-squat about Fiat. So insular that they don't realise whats going on across the pond. Fiat has by far the top management in the industry right now, AND the most advanced technology. All these good old boys rolling around the Nascar circuit don't realise how much Fiat have learned from their super-tech siblings.
GM already got out-foxed by Fiat more than once. Do not underestimate these guys.
