Dealers inspect their own cars, and many do it properly. The issue is not competence. It is that the inspection you are being shown was commissioned by the person selling you the vehicle.
Manufacturer certified pre-owned programmes have real standards, and a car that passes one has been through a genuine process. But the check is designed to establish that a vehicle meets a threshold for resale, not to give a buyer a full account of its condition.
A car can pass a multi-point check with tyres at the legal limit, brakes near the end of their life, and a repaired accident that was repaired competently. None of that is concealment. It is simply not what that inspection was for. Yours is.
Every inspection also covers the full checklist — engine, transmission, brakes, suspension, tyres, body and interior — with a diagnostic scan and a road test where the seller permits one.
Most will, and it is a routine request. Some will ask for an appointment. A dealer who refuses outright is telling you something worth listening to.
Often yes — not because the certification is meaningless, but because it answers a different question from the one you are asking.
That is what a great many customers do with it. A documented list of findings is a far stronger position than an opinion.
