2013 INFINITI JX35 BASE VIN 5N1AL0MM9DC312777

The Infiniti JX35 Base described here left the factory in 2013. Under the bonnet is a 3.5-litre petrol engine. The gearbox is automatic.

The recorded mileage is 141,711 miles. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. A service book or a folder of workshop invoices is the simplest place to find past readings.

When the car was recorded, it showed mechanical damage. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. With mechanical damage on file, the inspection should start with the engine, the gearbox and the running gear.

The record notes that the car ran and drove. A key is on file for the car.

Title status in the record: clean. Such a title means no salvage, flood or similar mark was recorded against the car; it does not rule out damage repaired without a claim.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. From the outside, a car with a repaired accident and a car without one can look identical.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. On a petrol engine, a rough idle, misfires or a warning light on the dashboard need looking into. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating. On a car with all-wheel drive, a whine or clunk when turning tightly at low speed needs a mechanic’s attention.

A history check works by VIN because the number never changes, unlike registration plates and owners. For this car, the VIN is 5N1AL0MM9DC312777. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

A VIN report gathers what different sources know about a car, such as the number of owners, mileage readings, damage and any branded title. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now. The next step is to look up the history behind VIN 5N1AL0MM9DC312777.
