2014 NISSAN FRONTIER SV VIN 1N6AD0ER4EN734728

This Nissan Frontier SV is a 2014 model, finished in white. Under the bonnet is a 4.0-litre petrol engine. The gearbox is automatic.

The source data puts the mileage at 102,854 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. 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. 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.

A note in the source data says the car did not run. The engine started, although the car is not confirmed as drivable. A key was there when the car was checked.

The record shows a salvage title. At some point in its life, the car was 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 the sum of what has happened to it since it was new, and most of it has left a trace on paper somewhere. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. A clean, polished car can still hide a serious accident, a flood or years of hard use.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. On a car that does not run, the automatic gearbox cannot be judged on the road; the colour and smell of its fluid and a diagnostic scan give the first clues.

The ninth character of the VIN is a check digit calculated from the other sixteen, so a mistyped or invented number does not add up. The VIN of this Nissan Frontier SV is 1N6AD0ER4EN734728. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. Paperwork is only as complete as the people who kept it, so a report with few entries lowers the risk without removing 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. For this 2014 Nissan Frontier SV, the sensible next step is a history check on VIN 1N6AD0ER4EN734728.
