2011 GMC CANYON SLE1 VIN 1GTH6MFE7B8129319

This GMC Canyon SLE1 was built in 2011. There is an automatic gearbox, with four-wheel drive. The petrol engine has five cylinders and produces 242 hp.

The source data puts the mileage at 171,760 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. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

The source data names no primary damage. That shows only that none was entered, so the body still deserves a close look. Water marks under the carpets, rust in unusual places or a panel in a slightly different shade would point to damage nobody ever entered.

A car that does not run has to be moved on a trailer, and its real condition is known only after a thorough assessment. An engine that will not start could have a simple electrical fault or internal damage, and only diagnostic work can tell which. A key was present.

According to the source data, the car has a clean title. 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. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. From the outside, a car with a repaired accident and a car without one can look identical.

When a car does not run, a compression test and the condition of the oil tell a mechanic whether the engine can be brought back to life. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. While the car does not run, stored fault codes and a look at the fluid are the only early evidence of how the automatic gearbox has fared. A car with four-wheel drive has extra differentials and often a transfer case, which an inspection should cover alongside the engine and gearbox.

The VIN is a 17-character code assigned at the factory: it identifies the manufacturer, the model and its variant, and ends with a serial number unique to the car. For this car, the VIN is 1GTH6MFE7B8129319. 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. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. A history report says nothing about the car’s present condition: the frame, corrosion, electrics and the quality of any repair are judged on a lift by a mechanic. A history check on VIN 1GTH6MFE7B8129319 is the place to start.
