2014 GMC YUKON XL 1500 DENALI VIN 1GKS1MEF9ER109378

This record covers a 2014 GMC Yukon XL 1500 Denali. The fuel is petrol. There is an automatic gearbox, with rear-wheel drive.

The clock stood at 247,763 miles when the data was entered. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. 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.

No primary damage is given in the record for this car, which is not the same as proof that it has never been damaged. Paint depth, panel gaps and the underbody show whether the body has been repaired.

A key was present.

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

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. 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.

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. The record gives the VIN as 1GKS1MEF9ER109378. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

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. A history check on VIN 1GKS1MEF9ER109378 is the place to start.
