2016 GMC SIERRA 1500 SLT VIN 1GTV2NEC3GZ156877

This entry is for a 2016 GMC Sierra 1500 SLT, finished in blue. The drivetrain combines an automatic gearbox with four-wheel drive. The petrol engine has eight cylinders and produces 355 hp. Every figure for this car is given as it appears in the source data.

At the time of recording, the car had covered 124,463 miles. The instruments count in miles; the same distance in kilometres is about 1.6 times the figure. Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

Primary damage in the record: all over the body. Whether the damage has been repaired since, and how well, is not something a damage entry can show. 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.

A car that does not run has to be moved on a trailer, and its real condition is known only after a thorough assessment. The engine did not start. A key was there when the car was checked. Months of standing can leave a car with seized brakes and perished tyres.

The car carries a clean title. With a clean title the car can be registered and insured in the usual way.

Behind every used car lies a string of events: who owned it and for how long, what the inspections found and which repairs and claims were made. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. A clean, polished car can still hide a serious accident, a flood or years of hard use.

Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. With no test drive possible, the automatic gearbox has to be assessed on a lift and with diagnostic equipment. Drive to all four wheels means more to maintain: differentials and couplings have oil of their own, which some manufacturers want changed at set intervals.

A vehicle identification number has 17 characters: the first three name the manufacturer, the next six describe the model and its specification, and the last eight identify the individual car. The record gives the VIN as 1GTV2NEC3GZ156877. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. 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 1GTV2NEC3GZ156877.
