1999 GMC YUKON SLT CMI VIN 1GKEK13R6XJ772530

This entry is for a 1999 GMC Yukon SLT CMI, finished in black. The gearbox is automatic. The petrol engine has eight cylinders and produces 255 hp. Every figure for this car is given as it appears in the source data.

The clock stood at 249,264 miles when the data was entered. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. A later figure lower than an earlier one points to a replaced instrument cluster or an odometer that has been wound back.

The main issue noted for this car is damage to the left front. Whether the damage has been repaired since, and how well, is not something a damage entry can show. Given the kind of damage entered, a mechanic should look first at the left front wing, the suspension on that corner and the wheel alignment.

The car is recorded as running and driving. A key is on file for 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.

According to the source data, the car has a salvage title. Titles of this type are issued to cars declared a total loss. Once issued, a branded title stays with the VIN for good, and it affects registration and insurance for every later owner.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating. A car with four-wheel drive has extra differentials and often a transfer case, which an inspection should cover alongside the engine and gearbox.

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 1GKEK13R6XJ772530. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. 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 1GKEK13R6XJ772530 first, and let what it shows guide the inspection.
