2018 MERCEDES-BENZ GLA 250 4MATIC VIN WDCTG4GB9JJ430185

This entry is for a 2018 Mercedes-Benz GLA 250 4MATIC, finished in blue. Power reaches the wheels through an automatic gearbox. The engine is a 2.0-litre petrol unit with four cylinders. The specification is taken from the source data and has not been checked against other documents.

The recorded mileage is 89,258 miles. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. 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. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

The record lists damage to the left rear as the main problem on this car. Whether the damage has been repaired since, and how well, is not something a damage entry can show. A lift and a diagnostic check show what photos cannot: bent brackets behind a panel, chafed wiring or deployed airbags.

At the time of recording, the car ran and drove. A key is on file for the car.

The car carries a clean title. There is no salvage or similar mark, so the car was never recorded as a total loss.

A car’s history is everything logged against it since it left the factory: registrations and owners, inspections, repairs and insurance claims. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

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, a rough idle, misfires or a warning light on the dashboard need looking into. 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. With all-wheel drive, mismatched tyres can strain the centre differential or coupling, so all four should be the same make and similarly worn.

A VIN never contains the letters I, O or Q, which could be mistaken for digits; its 17 characters identify the maker, the model and the individual car. This car’s identification number is WDCTG4GB9JJ430185. The number in the car’s documents should match the one stamped into the body and the one on the plate at the base of the windscreen.

A VIN report gathers what different sources know about a car, such as the number of owners, mileage readings, damage and any branded title. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair. The next step is to look up the history behind VIN WDCTG4GB9JJ430185.
