I did the big service on my Infiniti QX50 last week, and I want to share how it went. Before I booked, I could not find many real stories, only shop ads. The car has about sixty thousand kilometres, and I had been putting it off because the dealer quote scared me. A colleague who works near Musaffah told me to try an independent garage. I looked around and found a Top garage for Infiniti major and minor services in Musaffah. I did not trust the name alone, so I phoned two places and asked the same questions. What is included? Is the quote in writing? Will you show me the old parts? The first place gave me a vague answer. The second sent me a full list with the oil, filters, spark plugs, brake fluid and a full check, each with its own price. I picked that one. They kept the car most of the day. The mechanic showed me the old air filter, which was very dirty, and the brake fluid, which looked dark. Nothing extra was added at the end, and I got an itemised bill. The car feels a little smoother now, but maybe I am imagining it. How often do you repeat the major service? Is it worth changing the gearbox fluid at the same visit? If you did one lately, please tell me what you paid and what you would do differently.
