Learned the hard way once, now I won’t buy used without someone who actually

Learned the hard way once, now I won't buy used without someone who actually knows what to look forA few years back I bought a used BMW that looked amazing on the outside and the seller had a whole folder of receipts but it turned out half of them were from a shop that didn't even exist and I ended up stuck with a car that had a warped head and a transmission that was on its last legs, so now I'm finally in a position to get another car and I'm looking at a Lexus IS over in Deira that seems promising but there's just no way I'm going through that nightmare again, I need a proper Expert Pre Purchase Inspection Dubai service where someone goes over the thing with a fine tooth comb and checks the compression and the paint thickness and actually plugs into the computer to see if the mileage makes sense, because I'm tired of getting burned by sellers who are really good at polishing a turd and making it look like a cream puff, and I'd rather pay a bit now for a real inspection than spend the next six months regretting my decision every time a warning light pops on, anyone got a recommendation for a place that does a really thorough job and doesn't just give you a generic checklist with a few photos.
