Mercedes-Benz service FAQ
Will servicing my Mercedes-Benz here affect the factory warranty?
No. You can have maintenance done at any qualified independent shop. We follow the factory schedule, use OEM parts and fluids, and document every visit. Every maintenance and repair visit is also reported to CARFAX, so your service history stays complete for resale, just like a dealer.
Do you service Sprinter vans?
Yes. We maintain and repair Sprinter vans for both owners and businesses, including diesel emissions diagnostics.
