2012 INFINITI QX56 VIN JN8AZ2NC0C9317158

The Infiniti QX56 described here left the factory in 2012. The engine is a 5.6-litre petrol unit with eight cylinders. There is an automatic gearbox, with all-wheel drive. Every figure for this car is given as it appears in the source data.

The source data puts the mileage at 164,658 miles. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. Services and inspections note the distance covered, so a car with an ordinary past builds up a trail of figures that climb year after year. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

The record lists damage to the left rear as the main problem on this car. A damage entry is a starting point for the inspection, telling the mechanic where to look first.

A ‘runs and drives’ note means the car moved under its own power when it was checked. A key was noted with the car. Running condition describes a single moment, and standing or work done since can change it.

According to the source data, the car has a clean title. Nothing on the title points to a total loss or a flood.

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. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

An engine that has had its oil changed on time is far less likely to cause trouble later, and workshop invoices are the proof. On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was. With all-wheel drive, mismatched tyres can strain the centre differential or coupling, so all four should be the same make and similarly worn.

The tenth character of the VIN stands for the model year, and the eleventh for the plant that built the car. This Infiniti QX56 has the VIN JN8AZ2NC0C9317158. 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.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. For this 2012 Infiniti QX56, the sensible next step is a history check on VIN JN8AZ2NC0C9317158.
