Haven't had a chance to try the BlueTec models but I did try the ML320 CDI. It wasn't too bad (then again, with that much sound insulation, it's gonna be a quiet cabin anyway) but you can definitely hear the diesel clatter when you're standing next to it. I suspect the BlueTec diesels will be quieter even when you're standing next to the car. Not a fan of the front end redesign but the interior isn't too bad. This quote's funny
Yes, I enjoyed the review - esp. the paragraph you quoted. That was hysterical and very quick on the author's part.
