Interior assessment is divided into three core areas: the driver's high-frequency contact area (steering wheel, gear shift, edge of the driver's seat), central control button area, and rear seats and ceiling. The natural sheen of leather surfaces (patina) is normal; however, any physical damage (such as leather tearing, fabric burn holes, or plastic breakage) will be classified as "structural interior damage" and clearly marked.

Request a live video call during the test drive rather than a pre-recorded one. Cold start first: listen for rattling or metal scraping in the first seconds — possible timing chain or hydraulic lifter issues. During acceleration, a whining from the gearbox area can mean bearing wear; hesitation or jerking in an automatic suggests transmission problems. Braking: the pedal should feel firm, not spongy, and the car must not pull to one side. Turn the wheel fully in both directions and listen for clicking — a classic CV joint fault. Insist on a highway segment too: vibrations above 100 km/h often point to unbalanced wheels or bent rims. Ask the driver to film the dashboard throughout — warning lights that flicker on briefly are still faults that OBD will record.

A proper third-party inspection has four parts, and you should insist on all of them. 1. Lift inspection: the car goes on a hoist to examine the underbody, frame rails, suspension arms and oil pan for impact damage or leaks — areas no photo set can cover. 2. Paint thickness check: a gauge reading from every panel. Inconsistent or very high values reveal repainting; structural points like the A/B/C pillars matter most because they indicate accident repairs. 3. OBD diagnostics: fault codes and live data from the engine, transmission, ABS and airbag modules. Stored historical codes often tell the truth the dashboard hides. 4. Road test: cold and warm driving to check shifting, braking and unusual noises. The report should carry the VIN, inspection date and the agency's stamp or digital signature. It costs very little compared to the price of the car, and it filters out most problem vehicles before your money moves.
