I recently completed a Munich to Paris road trip in a BMW 335. When I returned to the US, I was retrospectively struck by the lack of high profile vehicles (pickup and SUV's, not celebrity Ferraris or Leclerc battle tanks) on French and German roads. I suppose when gas costs nearly seven bucks a gallon, fuel efficiency is all. Personally, I don't care for SUV's; the few I have owned have taught me that being tall and overweight is no more fun for a vehicle than it is for a former supermodel. So when my Mercedes dealer suggested I have a look at the new ML63, I scoffed. And then went along for the ride.
