1998 INFINITI I30 BASE VIN JNKCA21A1WT603722

This record covers a 1998 Infiniti I30 Base, finished in brown. There is an automatic gearbox, with front-wheel drive. 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 recorded mileage is 300,284 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. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

This Infiniti I30 Base is recorded with minor dents and scratches. A damage entry is a starting point for the inspection, telling the mechanic where to look first. Given the kind of damage entered, a mechanic should look first at the paintwork and whether any dent has reached the metal underneath.

When checked, the car could be started and driven under its own power. A key is on file for the car. 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.

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. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating.

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 JNKCA21A1WT603722. 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. A history report says nothing about the car’s present condition: the frame, corrosion, electrics and the quality of any repair are judged on a lift by a mechanic.
