2017 CADILLAC XT5 LUXURY VIN 1GYKNDRSXHZ267282

This Cadillac XT5 Luxury is a 2017 model. There is an automatic gearbox, with all-wheel drive. The engine is a 3.6-litre petrol unit with six cylinders. Every figure for this car is given as it appears in the source data.

The number on the clock proves little by itself; earlier figures logged at services and inspections are what make it believable. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

The record lists flood damage as the main problem on this car. The damage type is a short label: the extent of the damage and the quality of any repair still have to be judged on the car. Whatever the cause, a diagnostic scan of the car’s electronics shows fault codes that a visual check misses.

A key was present. 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.

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.

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. Automatic transmissions, CVTs included, are expensive to repair, so the test drive should include pulling away from a standstill and a stretch at motorway speed.

The VIN is a 17-character code assigned at the factory: it identifies the manufacturer, the model and its variant, and ends with a serial number unique to the car. For this car, the VIN is 1GYKNDRSXHZ267282. 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. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. 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. Before going any further with this Cadillac XT5 Luxury, it makes sense to look up VIN 1GYKNDRSXHZ267282.
