I'm going to see a 2017 Nissan Patrol this weekend in Umm Suqeim and the owner seems genuine, but I've heard enough stories about hidden problems that I want to be prepared. I'm not a mechanic and I don't want to rely purely on the seller's word or a quick test drive. Someone mentioned that there's Leading advice on hidden faults found in used cars in Umm Suqeim that covers the common issues people miss, and I'm planning to read through it before I go. But I'd also like to hear from anyone who's bought a used 4x4 in this area. What specific things should I be checking that aren't obvious? I'm thinking rust underneath, any signs of off road abuse, and whether the gearbox behaves properly when it's cold. Also, does anyone know a good independent inspector who covers Umm Suqeim without charging a fortune? Any tips would be really helpful because I don't want to make an expensive mistake.
