I think they actually are leaking a little, and i have 172k on the clock. Lots of highway miles but still...I guess I just want to know what my options are and how much out of pocket I am looking at for parts. A very good friend of mine is an S class specialist so as far as labor goes I'm in good shape (a good thing too because over the winter we gotta do the AC Evaporator core...ughhh) So anyone that knows, let me know...thanks again.

BTW, your cars are beautiful!
