2004 NISSAN SENTRA 1.8/1.8S VIN 3N1CB51D34L477247

This record covers a 2004 Nissan Sentra, finished in grey. The gearbox is automatic, with front-wheel drive. Power comes from a 1.8-litre petrol engine with four cylinders.

At the time of recording, the car had covered 211,521 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.

No damage entry is on file for this car. Signs of an old repair – uneven panel gaps, overspray, a slight mismatch in paint – can still turn up at an inspection.

A key is on file for the car. Months of standing can leave a car with seized brakes and perished tyres.

Title status in the record: clean. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

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. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. 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.

A VIN never contains the letters I, O or Q, which could be mistaken for digits; its 17 characters identify the maker, the model and the individual car. This car’s identification number is 3N1CB51D34L477247. The number in the car’s documents should match the one stamped into the body and the one on the plate at the base of the windscreen.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. 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.
