2013 INFINITI JX35 VIN 5N1AL0MM2DC347256

The Infiniti JX35 described here left the factory in 2013. The engine is a 3.5-litre petrol unit with six cylinders. The gearbox is automatic, with all-wheel drive.

The record gives the mileage as 188,079 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.

No primary damage is given in the record for this car, which is not the same as proof that it has never been damaged. Water marks under the carpets, rust in unusual places or a panel in a slightly different shade would point to damage nobody ever entered.

When it was checked, the car could not be driven. An engine that will not start could have a simple electrical fault or internal damage, and only diagnostic work can tell which. A key was noted with the car. Months of standing can leave a car with seized brakes and perished tyres.

Title status in the record: non-repairable. A title like this is issued when repair was judged uneconomical or unsafe. A branded title follows the car through every change of owner, so it remains part of its history.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

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. A car with all-wheel drive has extra differentials and often a transfer case, which an inspection should cover alongside the engine and gearbox.

Stamped into the body and printed on a plate, the VIN is the one identifier that stays with a car through every owner, registration and repair. The VIN on file for this car is 5N1AL0MM2DC347256. 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. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. The past is on file; the car’s condition today is a job for a mechanic, who can check the structure, underbody, electrics and any repairs on a lift.
