Thinking about picking up a second-hand SUV in Deira but terrified of getting burned

I've been browsing Dubizzle for the past couple of weeks trying to find a decent clean vehicle for my daily commute between Sharjah and Dubai, but every single car I look at has paint that looks way too fresh for its age or an engine bay that feels suspiciously scrubbed clean. My colleague was telling me last night that a lot of grey-market imports floating around the emirates have hidden flood damage or rolled-back mileage that seller photos will never show you, which has honestly set my anxiety off big time. I stumbled across pre purchase car inspection while reading through some older threads about red flags to check before handing over a deposit, and it really made me realize how easy it is to miss structural issues if you don't know what to look out for under the chassis. Getting Trusted advice on used car warning signs explained for Dubai buyers gave me a much better idea of what to inspect during a test drive, but I'm still debating whether I should just pay a certified technician to inspect the AC compressor and transmission properly before making any final offers.
