This week we welcome Charlie Hughes, the author of "Branding Iron" and an expert in automotive brands. In the past couple of years we've had a major culling of automotive marques--especially in Detroit. In this episode, we'll talk about what else can go: Acura? Infiniti? As usual, we'll also get into the news of the week. John McElroy's in studio with Peter De Lorenzo, the Autoextremist, and David Welch from Bloomberg BusinessWeek.
