I think I found a decent garage in Sharjah but I'm still nervous - any reviews?

So after weeks of asking around and reading forums, I finally took my 2014 Hyundai Santa Fe to a workshop in the Al Baja area that a coworker recommended. They seemed professional, gave me a printed estimate before starting any work, and even showed me the old parts after they were done. I got my oil changed, brakes done, and AC recharged for what seemed like a reasonable price, around 950 dirhams all in. The car feels fine so far but I've only driven it for a few days. The place is called Superior Vehicle Care Sharjah, at least that's what it said on the receipt. I'm trying to figure out if I got lucky or if they're actually consistently good because I need to get my transmission fluid changed next month and that's a bigger job. Has anyone here used this place for more than just basic maintenance? I'm especially curious about their diagnostic skills because my Santa Fe has an intermittent check engine light that comes on and off randomly. The mechanic said "probably an oxygen sensor" but didn't seem too sure. I don't want to throw money at parts if they're just guessing. Also wondering if they do proper transmission service with the correct fluid or if they just use generic stuff. I know Hyundais can be picky about that. Any experiences, good or bad, would really help me decide whether to go back or keep searching. Really hoping I finally found a trustworthy shop because driving to Dubai every time is killing me.
