Welcome to the forum & good 1st post. My Box has 105,K miles on it but I don't know what is recommended at that service since I do all the work on my car, usually before it is recommended. Don't want to send you away from this forum, but you should go to Rennlist.com forum & post in the Box forum there. You will get a response from Macster who lives in Livermore & has 257,K miles on his Box. He swears by dealer service but see if he can recommend a local independant. Tell him I sent you if you like.
