2015 NISSAN ALTIMA 2.5 S VIN 1N4AL3AP5FC489145

The Nissan Altima 2.5 S described here left the factory in 2015. Power comes from a 2.5-litre petrol engine with four cylinders. The drivetrain combines an automatic gearbox with front-wheel drive.

The recorded mileage is 108,832 miles. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. A later figure lower than an earlier one points to a replaced instrument cluster or an odometer that has been wound back. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

The main issue noted for this car is front-end damage. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Whatever the cause, a diagnostic scan of the car’s electronics shows fault codes that a visual check misses.

A ‘runs and drives’ note means the car moved under its own power when it was checked. A key was noted with the car. Condition notes are a snapshot: the car may have been worked on, stripped of parts or left standing since.

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. From the outside, a car with a repaired accident and a car without one can look identical.

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. 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.

A vehicle identification number has 17 characters: the first three name the manufacturer, the next six describe the model and its specification, and the last eight identify the individual car. The record gives the VIN as 1N4AL3AP5FC489145.

A VIN report gathers what different sources know about a car, such as the number of owners, mileage readings, damage and any branded title. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. The next step is to look up the history behind VIN 1N4AL3AP5FC489145.
