2015 MERCEDES-BENZ C 300 4MATIC VIN 55SWF4KB3FU037129

The Mercedes-Benz C 300 4MATIC described here left the factory in 2015. Under the bonnet is a 2.0-litre petrol engine. The drivetrain combines an automatic gearbox with all-wheel drive.

The clock stood at 94,709 miles when the data was entered. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. A later figure lower than an earlier one points to a replaced instrument cluster or an odometer that has been wound back. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

Primary damage in the record: minor dents and scratches. The damage type is a short label: the extent of the damage and the quality of any repair still have to be judged on the car. With minor dents and scratches on file, the inspection should start with the paintwork and whether any dent has reached the metal underneath.

A key is on file for the car. Months of standing can leave a car with seized brakes and perished tyres.

According to the source data, the car has a clean title. Nothing on the title points to a total loss or a flood.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. 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. On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. Automatic transmissions, CVTs included, are expensive to repair, so the test drive should include pulling away from a standstill and a stretch at motorway speed. On a car with all-wheel drive, a whine or clunk when turning tightly at low speed needs a mechanic’s attention.

The ninth character of the VIN is a check digit calculated from the other sixteen, so a mistyped or invented number does not add up. The VIN of this Mercedes-Benz C 300 4MATIC is 55SWF4KB3FU037129. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. A history report says nothing about the car’s present condition: the frame, corrosion, electrics and the quality of any repair are judged on a lift by a mechanic.
