New to Sharjah, where do locals actually take their cars for serious repairs?

I recently moved to Sharjah and I'm trying to get a feel for the best places to take my car for maintenance and repairs. I see small garages scattered around residential areas, but I get the impression that for more complex or serious work, people go elsewhere. A colleague mentioned that the industrial zones are the real hubs for automotive work. I found an article that confirms this, explaining why these areas have become the most popular repair locations in Sharjah for skilled, professional service. It highlighted the concentration of experienced technicians, proper diagnostic equipment, and the ability to handle major jobs like engine overhauls efficiently. It makes a lot of sense. Now I'm hoping to get some real-world advice from long-time residents. Which specific industrial zone would you recommend for finding a trustworthy mechanic? And do you have a particular workshop you've built a relationship with over the years?
