Without wishing to, or even dreaming of having a pi55ing contest......my ML had more creaks and rattles from the trim than almost any car I have owned, and to balance that statement my CLS was nigh on perfect in the trim department, silent and well screwed together (well apart from the glove box lid which was always in need of constant tweaking), the A6 I recently bought had so far been fautless inside (and outside thankfully) with the trim being IMO the best screwed together and solid feeling IME. And don't decry this a knocking as I never wanted to buy the Audi, it was the wifes major choice.......I just drive it
but frankly its an extremely impressive car. Bloody boring styling outside though...same old same old when it comes to Audi, but hey I am on the inside looking out
