2015 NISSAN SENTRA SV VIN 3N1AB7AP7FY251117

The Nissan Sentra SV described here left the factory in 2015. Under the bonnet is a 1.8-litre petrol engine. The drivetrain combines an automatic gearbox with front-wheel drive. Every figure for this car is given as it appears in the source data.

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.

The main issue noted for this car is side 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. 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.

Without a key, a modern car needs a replacement coded to its immobiliser before it can even be started. A condition note describes the car at one moment; months of standing or later work on the car can change the picture in either direction.

The record shows a salvage title. Titles of this type are issued to cars declared a total loss. If any work has been done on the car since, photos and invoices should show what was replaced.

A car’s history is everything logged against it since it left the factory: registrations and owners, inspections, repairs and insurance claims. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. 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 tenth character of the VIN stands for the model year, and the eleventh for the plant that built the car. This Nissan Sentra SV has the VIN 3N1AB7AP7FY251117. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair.
