2012 GMC ACADIA DENALI VIN 1GKKRTED9CJ233695

The GMC Acadia Denali described here left the factory in 2012. There is an automatic gearbox, with front-wheel drive. Power comes from a 3.6-litre petrol engine with six cylinders. The specification is taken from the source data and has not been checked against other documents.

The recorded mileage is 246,357 miles. The instruments count in miles; the same distance in kilometres is about 1.6 times the figure. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. A later figure lower than an earlier one points to a replaced instrument cluster or an odometer that has been wound back. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

When the car was recorded, it showed damage to the right rear. 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.

The record notes that the car ran and drove. A key was there when the car was checked. 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.

The car carries a clean title. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

A car’s history is the sum of what has happened to it since it was new, and most of it has left a trace on paper somewhere. 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 car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

An engine that has had its oil changed on time is far less likely to cause trouble later, and workshop invoices are the proof. 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 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. This GMC Acadia Denali has the VIN 1GKKRTED9CJ233695. 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 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.
