2015 INFINITI Q50 SPORT VIN JN1BV7AP4FM353201

The Infiniti Q50 Sport described here left the factory in 2015. The gearbox is automatic, with front-wheel drive. The engine is a 3.7-litre petrol unit with six cylinders.

The clock stood at 118,751 miles when the data was entered. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

The record lists side damage as the main problem on this car. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Some damage shows its consequences only later: corroded connectors and electrical faults can surface months afterwards.

A key was noted with the car. Months of standing can leave a car with seized brakes and perished tyres.

The record shows a salvage title. A title of this kind usually means the car was written off as a total loss after damage. If any work has been done on the car since, photos and invoices should show what was replaced.

Every car builds up a history from the day it is first registered: owners come and go, inspections are passed or failed, and repairs are paid for. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. A clean, polished car can still hide a serious accident, a flood or years of hard use.

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. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. 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.

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. The VIN on file for this car is JN1BV7AP4FM353201. The VIN usually appears at the base of the windscreen, on a door pillar and stamped into the body, and all of them should match the documents.

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 professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair.
