I totally agree with your thoughts
sunroof MUST be an optional I hate it while my wife loves it....
I had terrible experiences with it
just left the dealer with my brand new G55AMG I was driving on the highway and wifey opened it, after few miles was impossible to close it.... 20days of works on the car ...
now I own a GLE 53AMG with the sunroof and I never open
if must be in the car, much better not the glass one
driving a car with the sunroof it’s different, the car has a different twist
I felt this driving Porsches with and without sunroof
