I was about to buy a 2017 E Class from a private seller in Jumeirah, and the car looked flawless, low mileage, full service history, the whole package. Something told me to get it checked anyway, so I booked a Mercedes Pre Purchase Inspection Dubai through a company that a colleague recommended. The inspector found evidence of a poorly repaired rear impact that wasn't on any report, plus a failing engine mount and a small transmission leak that the seller conveniently forgot to mention. Walked away from that deal and saved myself at least 15k AED in hidden repairs. A few weeks later I bought a different car after a clean inspection, and I sleep easy knowing I didn't get ripped off. If you're buying a used Mercedes, don't trust the seller's word or a pretty polish. Spend the money on a real inspection from someone who knows these cars, it's the best investment you'll make in the buying process.
