Bought a used car in Al Nahda and now I'm second guessing everything

So I finally pulled the trigger on a 2018 Nissan Altima I found through a guy in Al Nahda. The price seemed fair, mileage was decent, and the seller was super chill during the test drive. But now that I've had it for a week I'm noticing small things like a slight vibration when braking and the AC taking a bit longer to cool than I expected. Nothing catastrophic but it's making me wonder if I should've been more careful. A friend mentioned he got a certified vehicle pre-purchase check in Al Nahda before buying his car and it saved him from a lemon with hidden accident damage. Honestly I didn't even know that was a thing until now. Is it too late to get something like that done after purchase just for peace of mind, or should I just take it to a regular garage? Also curious if anyone here has used 800sayara for inspections because I stumbled on their page while googling and the pricing seemed reasonable.
