2003 OLDSMOBILE ALERO GLS VIN 1G3NF52E33C245145

This Oldsmobile Alero GLS is a 2003 model, finished in red. The drivetrain combines an automatic gearbox with front-wheel drive. Power comes from a 3.4-litre petrol engine with six cylinders. Details for this car come from a single data source and may differ from its documents.

The source data puts the mileage at 104,582 miles. Miles and kilometres are easy to confuse, and a distance in miles looks lower than the same distance in kilometres. A car that has covered little distance for its age still ages: rubber seals, tyres and brake fluid deteriorate with time as well as use. Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

No primary damage is given in the record for this car, which is not the same as proof that it has never been damaged. Signs of an old repair – uneven panel gaps, overspray, a slight mismatch in paint – can still turn up at an inspection.

A ‘runs and drives’ note means the car moved under its own power when it was checked. A key was present. 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.

According to the source data, the car has a clean title. There is no salvage or similar mark, so the car was never recorded as a total loss.

A car’s history is the sum of what has happened to it since it was new, and most of it has left a trace on paper somewhere. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

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. 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.

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. The VIN on file for this car is 1G3NF52E33C245145. 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. Paperwork is only as complete as the people who kept it, so a report with few entries lowers the risk without removing 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.
