2016 NISSAN ALTIMA 2.5 S VIN 1N4AL3AP9GN349282

This Nissan Altima 2.5 S is a 2016 model, finished in silver. Under the bonnet is a 2.5-litre petrol engine. Power reaches the wheels through an automatic gearbox. Details for this car come from a single data source and may differ from its documents.

The source data puts the mileage at 208,867 miles. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. 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.

When the car was recorded, it showed front-end damage. 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. A lift and a diagnostic check show what photos cannot: bent brackets behind a panel, chafed wiring or deployed airbags.

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

The car carries a salvage title. Titles of this type are issued to cars declared a total loss. A branded title follows the car through every change of owner, so it remains part of its history.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. 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 car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

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.

Every modern car carries a 17-character VIN, its identity for life, and no two cars share one. This car’s identification number is 1N4AL3AP9GN349282. 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 shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. Paperwork is only as complete as the people who kept it, so a report with few entries lowers the risk without removing it. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now. A history check on VIN 1N4AL3AP9GN349282 is the place to start.
