I had chosen this option but apart from paying for it and it appearing on the invoice, there is no indication on the glass itelf that it is installed. I have noticed the car doesn't cook in the sun like my Maserati GT4200 did, but as the aircon in the M5 is so good, and it was so bad in the Maserati, I just don't know which is making my life better.
Does anyone know how you tell standard glass from comfort glass (?codes etched on the glass anywhere) once it is installed???
