2015 BUICK LACROSSE LEATHER VIN 1G4GB5G36FF153506

The Buick Lacrosse Leather described here left the factory in 2015. There is an automatic gearbox, with front-wheel drive. Power comes from a 3.6-litre petrol engine with six cylinders, rated at 304 hp. The specification is taken from the source data and has not been checked against other documents.

At the time of recording, the car had covered 175,519 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. A later figure lower than an earlier one points to a replaced instrument cluster or an odometer that has been wound back. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

The record lists damage to the right rear as the main problem on this car. 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.

The car is recorded as running and driving. A key was there when the car was checked. Condition notes are a snapshot: the car may have been worked on, stripped of parts or left standing since.

A clean title is on file for this car. Such a title means no salvage, flood or similar mark was recorded against the car; it does not rule out damage repaired without a claim.

Every car builds up a history from the day it is first registered: owners come and go, inspections are passed or failed, and repairs are paid for. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. From the outside, a car with a repaired accident and a car without one can look identical.

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. 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 history check works by VIN because the number never changes, unlike registration plates and owners. This car’s identification number is 1G4GB5G36FF153506. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. Before any decision, check what is known about VIN 1G4GB5G36FF153506.
