First Time VW Owner Here, Looking for Recommendations Before Summer Really Kicks In

So I just picked up my first Volkswagen a few weeks ago, a Tiguan, upgraded from a much older Japanese sedan I'd been driving for almost a decade, and while I'm loving the car so far there's a small part of me that's a little nervous about maintenance costs and finding the right people to actually work on it long term, coming from a car where basically every mechanic in town knew exactly what to do without even thinking twice, switching to something a bit more specialized feels like starting from scratch in terms of figuring out who to trust, my main concern right now is actually preventative rather than reactive, the AC in this Tiguan works great at the moment, no complaints at all, but I've read enough horror stories on here and other forums about European car AC systems acting up once they hit a certain age or mileage that I'd honestly rather find a reliable place now while everything's working fine rather than scrambling later during an actual emergency in the middle of summer when everyone's booked solid and stressed out, so I guess what I'm really asking is whether anyone here has recommendations for a place that specifically understands VW systems well enough to do proper preventative checks, not just reactive repairs after something's already broken, I've heard mixed things about general garages versus specialized ones, some people swear by generalists because they're cheaper and just as capable, while others insist that European cars specifically need someone who's genuinely familiar with the platform rather than someone applying general knowledge across every brand equally, which honestly makes sense to me logically but I don't have enough personal experience yet to know which camp I fall into, I did stumble across This Volkswagen AC repair service in Sharjah while searching around online last night and the way they described their approach to diagnostics seemed pretty thorough compared to a couple other places I looked at, mentioning things like proper pressure testing and actual VW specific tools rather than just generic AC servicing, which stood out to me since that's exactly the kind of attention to detail I was hoping to find rather than just a quick surface level check, still haven't committed to anywhere yet though since I wanted to get some outside opinions first before making a decision, especially from people who've actually owned VWs for a while and dealt with AC issues firsthand rather than just going off marketing descriptions alone, is preventative AC maintenance even something worth doing proactively or is it generally fine to just wait until an actual issue shows up before taking action, and if anyone has thoughts on generalist versus specialist garages specifically for European AC systems I'd genuinely appreciate hearing different perspectives before I settle into a routine with whichever place I end up choosing for the long run.
