2011 NISSAN FRONTIER SV VIN 1N6AD0ER3BC430393

This record covers a 2011 Nissan Frontier SV, finished in black. The gearbox is automatic. Power comes from a 4.0-litre petrol engine with six cylinders.

Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display.

No primary damage is given in the record for this car, which is not the same as proof that it has never been damaged. Paint depth, panel gaps and the underbody show whether the body has been repaired.

A note in the source data says the car did not run. The engine would not start, which can mean anything from a flat battery to serious mechanical damage. A key is on file for the car.

The car carries a non-repairable title. Titles of this type are issued to cars 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.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. 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.

When a car does not run, a compression test and the condition of the oil tell a mechanic whether the engine can be brought back to life. 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 record gives the VIN as 1N6AD0ER3BC430393. 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 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. Before going any further with this Nissan Frontier SV, it makes sense to look up VIN 1N6AD0ER3BC430393.
