2015 MERCEDES-BENZ ML 350 4MATIC VIN 4JGDA5HBXFA567946

This record covers a 2015 Mercedes-Benz ML 350 4MATIC. Power reaches the wheels through an automatic gearbox. The petrol engine has six cylinders.

The clock stood at 155,814 miles when the data was entered. Services and inspections note the distance covered, so a car with an ordinary past builds up a trail of figures that climb year after year. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

This Mercedes-Benz ML 350 4MATIC is recorded with minor dents and scratches. A damage entry is a starting point for the inspection, telling the mechanic where to look first. Damage rarely stays where it is first seen: an impact can reach the mountings and airbags behind a panel, and water or fire the wiring and electronics.

At the time of recording, the car ran and drove. A key was there when the car was checked. Months of standing can leave a car with seized brakes and perished tyres.

Behind every used car lies a string of events: who owned it and for how long, what the inspections found and which repairs and claims were made. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

A cold start, the colour of the exhaust smoke and any oil leaks tell a mechanic a good deal about how an engine has been treated. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was. Drive to all four wheels means more to maintain: differentials and couplings have oil of their own, which some manufacturers want changed at set intervals.

The VIN is a 17-character code assigned at the factory: it identifies the manufacturer, the model and its variant, and ends with a serial number unique to the car. This car’s identification number is 4JGDA5HBXFA567946. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now.
