2015 BUICK LACROSSE VIN 1G4GB5GR1FF150906

This record covers a 2015 Buick Lacrosse, finished in white. There is an automatic gearbox, with front-wheel drive. A 2.4-litre engine works together with an electric motor.

The record gives the mileage as 124,242 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.

In the source data, the main issue is minor dents and scratches. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. 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 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.

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. From the outside, a car with a repaired accident and a car without one can look identical.

An engine that has had its oil changed on time is far less likely to cause trouble later, and workshop invoices are the proof. A hybrid adds a traction battery to the engine, and its condition deserves a check of its own. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was.

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 record gives the VIN as 1G4GB5GR1FF150906. 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.
