2015 INFINITI Q50 PREMIUM VIN JN1BV7AR1FM418524

This entry is for a 2015 Infiniti Q50 Premium. The gearbox is automatic, with all-wheel drive. Power comes from a 3.7-litre petrol engine with six cylinders, rated at 328 hp.

At the time of recording, the car had covered 109,844 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. 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.

Primary damage in the record: front end. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Damage rarely stays where it is first seen: an impact can reach the mountings and airbags behind a panel, and water or fire the wiring and electronics.

The record notes that the car ran and drove. A key was present.

The record shows a non-repairable title. A title of this kind usually means the car was written off as a total loss after damage. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title, however sound the car looks.

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. From the outside, a car with a repaired accident and a car without one can look identical.

A cold start, the colour of the exhaust smoke and any oil leaks tell a mechanic a good deal about how an engine has been treated. A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. 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.

A history check works by VIN because the number never changes, unlike registration plates and owners. This car’s identification number is JN1BV7AR1FM418524. 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. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list 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 JN1BV7AR1FM418524 is the place to start.
