2011 CADILLAC CTS VIN 1G6DC5EY1B0167056

The Cadillac CTS described here left the factory in 2011. Under the bonnet is a 3.0-litre petrol engine. Power reaches the wheels through an automatic gearbox. The specification is taken from the source data.

At the time of recording, the car had covered 159,229 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

This Cadillac CTS is recorded with minor dents and scratches. 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.

At the time of recording, the car ran and drove. 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: clean. Nothing on the title points to a total loss or a flood.

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. Pieces of a car’s history sit with registries, dealers, workshops and insurance companies, and none of them sees the whole picture. A clean, polished car can still hide a serious accident, a flood or years of hard use.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating. Drive to all four wheels means more to maintain: differentials and couplings have oil of their own, which some manufacturers want changed at set intervals.

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 1G6DC5EY1B0167056. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. The past is on file; the car’s condition today is a job for a mechanic, who can check the structure, underbody, electrics and any repairs on a lift.
