2019 INFINITI Q50 3.0T LUXE VIN JN1EV7AP9KM514679

The Infiniti Q50 3.0T Luxe described here left the factory in 2019. Power reaches the wheels through an automatic gearbox. Under the bonnet is a 3.0-litre petrol engine. Every figure for this car is given as it appears in the source data.

The source data puts the mileage at 122,461 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

Primary damage in the record: flood. 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. A condition note describes the car at one moment; months of standing or later work on the car can change the picture in either direction.

A car’s history is the sum of what has happened to it since it was new, and most of it has left a trace on paper somewhere. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

For the engine, the service history matters most: oil changes, filters and the timing belt or chain are the entries to look for. A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. Automatic transmissions, CVTs included, are expensive to repair, so the test drive should include pulling away from a standstill and a stretch at motorway speed.

A history check works by VIN because the number never changes, unlike registration plates and owners. For this car, the VIN is JN1EV7AP9KM514679. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

A VIN report gathers what different sources know about a car, such as the number of owners, mileage readings, damage and any branded title. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. 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.
