Looking for Honest Advice Before Booking My Next Range Rover Repair

My Range Rover has been making a strange noise whenever I drive over small bumps, and it has been getting worse over the last few weeks. I already visited one garage, but they gave me a very expensive quote without clearly explaining what was wrong. That experience made me more careful about choosing where to take the car next. Since then, I have been reading reviews and checking what other owners recommend before making another decision. While searching online, I came across and noticed it focuses on this type of vehicle. I have not booked anything yet, so I wanted to ask if anyone here has used them before. Did they find the problem quickly, and were they honest about what actually needed to be repaired? I do not mind paying for quality work, but I want to avoid replacing parts that are still in good condition. I also appreciate mechanics who explain everything in simple words instead of using technical terms that most people do not understand. Good communication is just as important as good repair work. If anyone has personal experience with this workshop or can recommend another place that really understands Range Rovers, I would be happy to hear your thoughts before I make my appointment visit here caracrepairsharjah.ae/brands/range-rover.
I'm hoping someone here can point me in the right direction because I've been going around in circles trying to find a reliable mechanic for my Audi in Sharjah. I've got a 2016 A6 that's started shifting rough between third and fourth gear, and there's a slight hesitation when I accelerate from a stop that wasn't there before. I took it to a garage in Al Nahda and they quoted me a crazy amount for a full rebuild without even properly diagnosing it, just a quick drive and a guess. I've heard there are some proper specialists in Industrial Area 4 that actually know these ZF transmissions inside out. One place I found online is Burj Malabar Auto Maintenance on 13 Street #44, and their reviews mention German-trained technicians and OEM parts. Another shop called AMA AUTO on 21 Street #23 seems to have really good feedback from Audi owners, with one review specifically mentioning transmission work on an A8. I've also come across gearboxrepairsharjah.ae/brands/audi/, which lists Audi as one of the brands they specialize in and they're based in Industrial Area. Has anyone actually used any of these places and can vouch for their work? I just want someone who'll do a proper diagnostic and give me an honest answer about what's actually wrong, not just throw a rebuild quote at me. Any advice would be massively appreciated. Thanks.
