Yep, I ran into the same issue when I first moved here. It’s confusing when you don’t know which showroom is worth visiting. I found a helpful resource:
https://auto.ae/showrooms/all/?page=1 — it’s a full list of UAE showrooms you can scroll through. Saves so much time, and you can get an idea of what each has to offer before committing to a visit. I actually used it to find a dealer in Abu Dhabi where I got my Mitsubishi Outlander at a fair price.
