2012 NISSAN ALTIMA SR VIN 1N4BL2AP7CC102508

This Nissan Altima SR was built in 2012. Under the bonnet is a 3.5-litre petrol engine. Power reaches the wheels through an automatic gearbox. Every figure for this car is given as it appears in the source data.

The clock stood at 163,617 miles when the data was entered. 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. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

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. Given the kind of damage entered, a mechanic should look first at the radiator support, the headlamp mountings and the front crash structure.

The record notes that the car ran and drove. A key was there when the car was checked.

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. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. From the outside, a car with a repaired accident and a car without one can look identical.

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. 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 vehicle identification number has 17 characters: the first three name the manufacturer, the next six describe the model and its specification, and the last eight identify the individual car. For this car, the VIN is 1N4BL2AP7CC102508. 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.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. 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. The next step is to look up the history behind VIN 1N4BL2AP7CC102508.
