2011 GMC YUKON SLE VIN 1GKS2AE08BR171390

The GMC Yukon SLE described here left the factory in 2011. The car runs on petrol or ethanol. Power reaches the wheels through an automatic gearbox. Every figure for this car is given as it appears in the source data.

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.

Primary damage in the record: front end. A damage entry is a starting point for the inspection, telling the mechanic where to look first. Whatever the cause, a diagnostic scan of the car’s electronics shows fault codes that a visual check misses.

As a non-runner, the car needs its engine, gearbox and electrics assessed before anything else. The engine could not be started. 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.

A salvage title is on file for this car. A title like this is issued when repair was judged uneconomical or unsafe. 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. A clean, polished car can still hide a serious accident, a flood or years of hard use.

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. On a car that does not run, the automatic gearbox cannot be judged on the road; the colour and smell of its fluid and a diagnostic scan give the first clues. A car with four-wheel drive has extra differentials and often a transfer case, which an inspection should cover alongside the engine and gearbox.

Stamped into the body and printed on a plate, the VIN is the one identifier that stays with a car through every owner, registration and repair. The record gives the VIN as 1GKS2AE08BR171390. The VIN usually appears at the base of the windscreen, on a door pillar and stamped into the body, and all of them should match the documents.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. 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. Look up the history of VIN 1GKS2AE08BR171390 first, and let what it shows guide the inspection.
