2011 BUICK LACROSSE CXL VIN 1G4GC5ED0BF336161

This Buick Lacrosse CXL was built in 2011. The petrol engine has six cylinders. Power reaches the wheels through an automatic gearbox. The specification is taken from the source data and has not been checked against other documents.

The number on the clock proves little by itself; earlier figures logged at services and inspections are what make it believable. 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 fire damage. Two cars with the same damage label can be very different: one needs a few new parts, the other major work.

No key is recorded with the car, and a replacement has to be coded to the immobiliser. 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 car carries a salvage title. At some point in its life, the car was declared a total loss. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title.

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. Pieces of a car’s history sit with registries, dealers, workshops and insurance companies, and none of them sees the whole picture. 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. On a petrol engine, a rough idle, misfires or a warning light on the dashboard need looking into. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating.

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. This Buick Lacrosse CXL has the VIN 1G4GC5ED0BF336161. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

A VIN report gathers what different sources know about a car, such as the number of owners, mileage readings, damage and any branded title. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. 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 1G4GC5ED0BF336161.
