2018 GMC SIERRA K1500 SLT VIN 3GTU2NEC8JG457731

The GMC Sierra K1500 SLT described here left the factory in 2018. The engine is a 5.3-litre petrol unit with eight cylinders. The gearbox is automatic, with four-wheel drive. The specification is taken from the source data.

The record gives the mileage as 123,688 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. Services and inspections note the distance covered, so a car with an ordinary past builds up a trail of figures that climb year after year. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

The main issue noted for this car is rear-end damage. Two cars with the same damage label can be very different: one needs a few new parts, the other major work.

A ‘runs and drives’ note means the car moved under its own power when it was checked. A key was noted with the car. 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.

Title status in the record: salvage. A title of this kind usually means the car was written off as a total loss after damage. If any work has been done on the car since, photos and invoices should show what was replaced.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. A clean, polished car can still hide a serious accident, a flood or years of hard use.

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, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. 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. With four-wheel drive, mismatched tyres can strain the centre differential or coupling, so all four should be the same make and similarly worn.

The tenth character of the VIN stands for the model year, and the eleventh for the plant that built the car. This car’s identification number is 3GTU2NEC8JG457731. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. Paperwork is only as complete as the people who kept it, so a report with few entries lowers the risk without removing it. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair. Look up the history of VIN 3GTU2NEC8JG457731 first, and let what it shows guide the inspection.
