2014 GMC SIERRA 1500 SLE VIN 3GTP1UEH2EG538347

The GMC Sierra 1500 SLE described here left the factory in 2014. 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 clock stood at 135,034 miles when the data was entered. The instruments count in miles; the same distance in kilometres is about 1.6 times the figure. 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.

Primary damage in the record: right side. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. With damage to the right side on file, the inspection should start with the pillars, sills and doors on the right side.

At the time of recording, the car ran and drove. A key is on file for the car. Months of standing can leave a car with seized brakes and perished tyres.

The record shows a salvage title. Titles of this type are issued to cars declared a total loss. A branded title follows the car through every change of owner, so it remains part of its history.

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. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

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 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 VIN on file for this car is 3GTP1UEH2EG538347. The number in the car’s documents should match the one stamped into the body and the one on the plate at the base of the windscreen.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair. The next step is to look up the history behind VIN 3GTP1UEH2EG538347.
