Randy's American Car Care Center
452 SE Main St.
Willamina, OR 97396
Just north of the eastern junction of Hwy 22 and 18. If you are headed to the Oregon Coast from Salem, it's on the way.
Randy's has a qualified Sprinter mechanic and lifts that can handle all Sprinters and Sprinter-based RVs, because the Spirit Mountain Casino uses a large number of Sprinters as shuttles. I've used Randy's for most of my maintenance and non-warranty work. Excellent service.
