Welcome to
GCZ mate, you will definitely have a great time here. I do agree with your in-laws, once you have a Merc you don't want to go back, I am guessing the R-class is your 1st MB? Thanks for sharing your impressions of your car, no doubt you will grow to appreciate it even more in time. It is true that the R-class isn't a favourite among the MB fans in here, but you can provide us a more balanced view of the car.
mind if you share some photos with us?
