2015 CADILLAC CTS LUXURY VIN 1G6AR5SX1F0103425

The Cadillac CTS Luxury described here left the factory in 2015. Power reaches the wheels through an automatic gearbox. Under the bonnet is a 2.0-litre petrol engine producing 272 hp. Every figure for this car is given as it appears in the source data.

The source data puts the mileage at 119,317 miles. Miles and kilometres are easy to confuse, and a distance in miles looks lower than the same distance in kilometres. A later figure lower than an earlier one points to a replaced instrument cluster or an odometer that has been wound back. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

No primary damage is given in the record for this car, which is not the same as proof that it has never been damaged. Signs of an old repair – uneven panel gaps, overspray, a slight mismatch in paint – can still turn up at an inspection.

A key was there when the car was checked. Condition notes are a snapshot: the car may have been worked on, stripped of parts or left standing since.

A clean title is on file for this car. With a clean title the car can be registered and insured in the usual way.

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. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

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. On a petrol engine, a rough idle, misfires or a warning light on the dashboard need looking into. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was.

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 Cadillac CTS Luxury has the VIN 1G6AR5SX1F0103425. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. 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.
