2020 NISSAN ALTIMA SR FWD VIN 1N4BL4CV3LC153852

This entry is for a 2020 Nissan Altima SR FWD, finished in black. Power reaches the wheels through an automatic gearbox. The fuel is petrol. Every figure for this car is given as it appears in the source data.

The clock stood at 135,921 miles when the data was entered. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

The record lists front-end damage as the main problem on this car. A damage entry is a starting point for the inspection, telling the mechanic where to look first. A lift and a diagnostic check show what photos cannot: bent brackets behind a panel, chafed wiring or deployed airbags.

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.

A salvage title is on file for this car. A title like this is issued when repair was judged uneconomical or unsafe. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

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. 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.

Every modern car carries a 17-character VIN, its identity for life, and no two cars share one. The VIN on file for this car is 1N4BL4CV3LC153852. 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 repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now. With this 2020 Nissan Altima SR FWD, the first step is a look at the history behind VIN 1N4BL4CV3LC153852.
