2012 GMC SIERRA 2500HD SLE VIN 1GT220C88CZ248369

The GMC Sierra 2500HD SLE described here left the factory in 2012. Under the bonnet is a 6.6-litre diesel engine. The gearbox is automatic. The specification is taken from the source data.

The car was recorded with 278,595 miles on the clock. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. 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.

The record lists flood damage as the main problem on this car. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Whatever the cause, a diagnostic scan of the car’s electronics shows fault codes that a visual check misses.

The record notes that the car ran and drove. 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.

Title status in the record: salvage. At some point in its life, the car was 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.

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. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

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. A diesel used mainly for short trips may need attention to its particulate filter, EGR valve or injectors. 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 of this GMC Sierra 2500HD SLE is 1GT220C88CZ248369. 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. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now.
