2015 BUICK REGAL TURBO/E-ASSIST PREMIUM I VIN 2G4GN5EX7F9296874

This record covers a 2015 Buick Regal. The drivetrain combines an automatic gearbox with front-wheel drive. Under the bonnet is a 2.0-litre petrol engine.

The source data puts the mileage at 122,615 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. The number on the clock proves little by itself; earlier figures logged at services and inspections are what make it believable. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

Primary damage in the record: front end. A damage entry is a starting point for the inspection, telling the mechanic where to look first. Damage rarely stays where it is first seen: an impact can reach the mountings and airbags behind a panel, and water or fire the wiring and electronics.

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

The record shows a clean title. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

A car’s history is everything logged against it since it left the factory: registrations and owners, inspections, repairs and insurance claims. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. 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. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. 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. The VIN on file for this car is 2G4GN5EX7F9296874. 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.

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. The past is on file; the car’s condition today is a job for a mechanic, who can check the structure, underbody, electrics and any repairs on a lift.
