The mechanics immediately diagnosed the noise and explained in detail the cause. It turned out that the problem was a worn exhaust system component. I was pleased that they didn't push unnecessary work, but offered the best solution. The repair was done carefully and quickly. Afterward, the car became noticeably quieter, and the engine sound became smooth and pleasant again. I'd especially like to highlight their customer service—the staff were polite, explained everything clearly, and kept me updated on the repair process. It's clear they really know their business. I was also pleasantly surprised by the cleanliness of the shop and the organization of the work.
