I got a shiny blue 335i loaner from the dealer today when I dropped off my X5 for a 30K mile service. The loaner paperwork says it's a 2007 model. I'm wondering if this is the one with the twin-turbo V6, or was that not available on the 2007? All I know is it's fast as all hell and throws me back in my seat when I gun the throttle. The acceleration is unreal. I didn't bother to look under the hood yet since I was in a hurry to get to work.
