I too fell foul with the sunroof issue. I ordered a B200 AMG Premium Plus back in December but was told in early April that it could be months before it turns up if at all. However, the dealer could lay his hands on a B200 AMG Premium in Iridium Silver within a matter of days. Much as I would have liked the sunroof the car really did tick all my boxes so I accepted that offer. Picked it up last week and the smile has not left my face since! Really pleased with it although it will probably take me 3 years to work out all the tech. The smaller engine does not seem to be a problem although it’s normally just me in the car. The car feels very good quality and although it is classed as an SUV it drives more like a saloon. My last car was a Touran which was more of a workhorse so I’m enjoying the extra luxury.
