2021 NISSAN ALTIMA SR VIN 1N4BL4CW6MN420822

The Nissan Altima SR described here left the factory in 2021. The gearbox is continuously variable (CVT). Under the bonnet is a 2.5-litre petrol engine. Every figure for this car is given as it appears in the source data.

The source data puts the mileage at 36,921 miles. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. Gaps of several years between logged figures deserve attention, as does any reading lower than the one before it. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

The main issue noted for this car is rear-end damage. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. Given the kind of damage entered, a mechanic should look first at the boot floor, the rear panel and the chassis rails.

The car is recorded as running and driving. A key was there when the car was checked.

The record shows a salvage title. Titles of this type are issued to cars declared a total loss. A branded title follows the car through every change of owner, so it remains part of its history.

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. 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. On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. 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. On a car with four-wheel drive, a whine or clunk when turning tightly at low speed needs a mechanic’s attention.

Stamped into the body and printed on a plate, the VIN is the one identifier that stays with a car through every owner, registration and repair. For this car, the VIN is 1N4BL4CW6MN420822. 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.

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. With this 2021 Nissan Altima SR, the first step is a look at the history behind VIN 1N4BL4CW6MN420822.
