1) Does the laminated glazing also bring advantages in terms of indoor noise or is it only of advantage in terms of thermal protection. Does anyone have practical experience ? I find it a pity that this option only exists in connection with the darkened windows. 2) Does one of you not have Airmatic and drives the new standard steel suspension all around ? Are there experiences here compared to Airmatic ! 3) How to evaluate the sound system ? Of course compared to the Standard equipment ! Thank you for your hopefully knowledgeable answer. Unfortunately, the MB seller could not answer these questions. Frank
