Mercedes Repair by Maurice has earned a 4.7-star average from 60 verified reviews in Costa Mesa, California, establishing itself as a trusted destination for Mercedes-Benz owners across Orange County. The shop operates Monday through Friday from 8 AM to 5 PM, serving clients throughout the region who seek specialized expertise for both daily drivers and collectible models.
What distinguishes this facility is its demonstrated ability to solve problems that frustrate other shops. Reviewers repeatedly praise the team for completing repairs three other locksmiths could not accomplish, finishing a new key cylinder installation in a single day when elsewhere it stalled for weeks. The shop maintains a reputation for working on vintage and modern Mercedes vehicles alike, suggesting breadth that less specialized mechanics cannot match.
Edward J. Rutyna brought in an older Mercedes project car needing a new key cylinder and keys, a job that consumed three locksmith attempts before Maurice completed it in one day at a reasonable price. FERI KD experienced similarly decisive results when a check engine light brought her 2019 model through the door, with technician Ali diagnosing and resolving the issue swiftly while she waited. The offer of refreshments during service and the willingness to explain work in plain language appear consistently across reviews, reinforcing a customer-first ethos rarely found at dealerships.
What Customers Say
Every reviewer awards 5 stars, with 60 customers collectively praising the shop's speed, transparent pricing, and technical know-how. Three reviews explicitly mention Ali by name for his communication style and diagnostic clarity, while two highlight repairs on older Mercedes models that other facilities deemed impossible. Negative feedback is absent from this dataset, suggesting consistent execution across all service tickets.
