2015 NISSAN SENTRA SR VIN 3N1AB7AP6FY307872

This record covers a 2015 Nissan Sentra SR. There is an automatic gearbox, with front-wheel drive. Power comes from a 1.8-litre petrol engine with four cylinders. Details for this car come from a single data source and may differ from its documents.

The clock stood at 297,453 miles when the data was entered. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

The record lists rear-end damage 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. 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.

When checked, the car could be started and driven under its own power. A key was noted with the car. Months of standing can leave a car with seized brakes and perished tyres.

The car carries a salvage title. A title like this is issued when repair was judged uneconomical or unsafe.

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. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. 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.

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 3N1AB7AP6FY307872. 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.

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 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.
