Fiat 500 owners in Sharjah – do any of you actually trust a normal garage?

I’m the proud but constantly stressed owner of a 2014 Fiat 500 TwinAir and honestly I love the little thing for zipping around Sharjah, but every time something goes wrong I get the same reaction from mechanics – either they laugh and say “why did you buy this” or they pretend to know what they’re doing and make things worse. Last month I had a weird misfire and a shop in Industrial Area 4 replaced all four spark plugs and two coil packs only for the problem to come back three days later, turns out it was just a failing fuel injector that they could have found with proper diagnostics. Someone at a car meet told me about the Best Fiat Car Repair Sharjah and said they actually have the MultiAir software to properly diagnose those tricky 0.9L engines and even stock common parts like the oil pressure switches that always fail. I’m planning to take my car there next week for a full inspection but I’m curious if anyone has firsthand experience with them for something like a stuck wastegate or a failed dualogic transmission? Really tired of being treated like a weirdo just for driving something different.
