2016 NISSAN SENTRA S VIN 3N1AB7AP6GY288872

This Nissan Sentra S was built in 2016. Power comes from a 1.8-litre petrol engine with four cylinders. There is an automatic gearbox, with front-wheel drive. The specification is taken from the source data and has not been checked against other documents.

The source data puts the mileage at 68,519 miles. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

In the source data, the main issue is front-end damage. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. Given the kind of damage entered, a mechanic should look first at the radiator support, the headlamp mountings and the front crash structure.

A key was there when the car was checked. Months of standing can leave a car with seized brakes and perished tyres.

A salvage title is on file for this car. At some point in its life, the car was declared a total loss. Once issued, a branded title stays with the VIN for good, and it affects registration and insurance for every later owner.

A car’s history is everything logged against it since it left the factory: registrations and owners, inspections, repairs and insurance claims. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. A clean, polished car can still hide a serious accident, a flood or years of hard use.

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. A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. 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 tenth character of the VIN stands for the model year, and the eleventh for the plant that built the car. This car’s identification number is 3N1AB7AP6GY288872. The VIN usually appears at the base of the windscreen, on a door pillar and stamped into the body, and all of them should match the documents.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair. Look up the history of VIN 3N1AB7AP6GY288872 first, and let what it shows guide the inspection.
