I just purchased MB engine battery for $169, Freightliner McCoy only sales AGM for over $220, Salem was $190. Have scheduled oil change in a few days for $225.
Went to Wilsonville Mercedes shop – replaced oil/filter, 2016020007 Software update, 2017030012 air-bag replaced, complementary multi point inspection checked OK – total $225. For todays visit I would rate them at an excellent level, even included free massage in the waiting room.
