Consulting your owner’s manual for specific fluid types and intervals is always recommended.
Mercedes B3 Service Cost: What to Budget
The cost of Mercedes-Benz Service B3 can vary depending on several factors, including your specific Mercedes-Benz model, the location of the service center (dealership vs. independent mechanic), and local labor rates. However, you can generally expect to pay between $200 and $450 for a complete Mercedes B3 service.
