1986 BUICK RIVIERA VIN 1G4EZ57B2GU412550

This Buick Riviera is a 1986 model. Power reaches the wheels through an automatic gearbox. The car runs on petrol. Details for this car come from a single data source and may differ from its documents.

The record gives the mileage as 63,172 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 little distance for its age still ages: rubber seals, tyres and brake fluid deteriorate with time as well as use. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

When the car was recorded, it showed mechanical damage. 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.

The record notes that the car ran and drove. A key was there when the car was checked.

Title status in the record: clean. Nothing on the title points to a total loss or a flood.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. 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.

The tenth character of the VIN stands for the model year, and the eleventh for the plant that built the car. The record gives the VIN as 1G4EZ57B2GU412550.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. 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.
