I was charged $22 by my MB dealer. However, they get their parts the next day... which is why I ain't complaining. The guy remembers me that he even said "I know you'll come by so I took the parts out in the morning.. :p"
I did have to wait about a month for a foot rest!! Apprently it was imported from germany! Oh well, took a while but good to know that every single part I need for the car is still available.
