2012 CADILLAC SRX LUXURY COLLECTION VIN 3GYFNAE30CS643170

This Cadillac SRX Luxury Collection is a 2012 model. The engine is a 3.6-litre petrol unit with six cylinders. The gearbox is automatic.

The clock stood at 93,075 miles when the data was entered. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. 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 main issue noted for this car is front-end damage. Whether the damage has been repaired since, and how well, is not something a damage entry can show. A lift and a diagnostic check show what photos cannot: bent brackets behind a panel, chafed wiring or deployed airbags.

When checked, the car could be started and driven under its own power. A key was present. Months of standing can leave a car with seized brakes and perished tyres.

The car carries a clean title. Such a title means no salvage, flood or similar mark was recorded against the car; it does not rule out damage repaired without a claim.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. Pieces of a car’s history sit with registries, dealers, workshops and insurance companies, and none of them sees the whole picture. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. 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. For this car, the VIN is 3GYFNAE30CS643170. 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.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair. Look up the history of VIN 3GYFNAE30CS643170 first, and let what it shows guide the inspection.
