2013 INFINITI JX35 VIN 5N1AL0MM1DC341917

The Infiniti JX35 described here left the factory in 2013. There is an automatic gearbox, with all-wheel drive. The engine is a 3.5-litre petrol unit with six cylinders. Details for this car come from a single data source and may differ from its documents.

A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

When the car was recorded, it showed rollover damage. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. Some damage shows its consequences only later: corroded connectors and electrical faults can surface months afterwards.

A car that does not run has to be moved on a trailer, and its real condition is known only after a thorough assessment. The engine would not start, which can mean anything from a flat battery to serious mechanical damage. Without a key, a modern car needs a replacement coded to its immobiliser before it can even be started. Months of standing can leave a car with seized brakes and perished tyres.

The car carries a salvage title. Titles of this type are issued to cars declared a total loss. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title.

Behind every used car lies a string of events: who owned it and for how long, what the inspections found and which repairs and claims were made. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

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. With no test drive possible, the automatic gearbox has to be assessed on a lift and with diagnostic equipment. Drive to all four wheels means more to maintain: differentials and couplings have oil of their own, which some manufacturers want changed at set intervals.

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. For this car, the VIN is 5N1AL0MM1DC341917. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. Paperwork is only as complete as the people who kept it, so a report with few entries lowers the risk without removing it. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair. A history check on VIN 5N1AL0MM1DC341917 is the place to start.
