the little twisty thing on the side of my 2012 E63 dash that is used to adjust brightness, is it just my car or does it feel like its going to fall off and all flimsy in all your cars

 

When I got the car last year, I also thought that part is a little flimsy. They could have it similar to this button in my 20 years old Nissan where pressing the top increases the brightness and vice versa. Or at least make it more robust.

 

I hear ya! When I owned my GTR a lot of my buddies who got there porsche asses handed to them would be like yeah but it's a Nissan and the interior is cheap! But in reality there isn't one cheap feeling part in that car like there is in my E63

 

It has never changed in any of our mercs
