2010 CADILLAC SRX LUXURY COLLECTION VIN 3GYFNAEY3AS586634

This Cadillac SRX Luxury Collection was built in 2010. Power comes from a 3.0-litre petrol engine with six cylinders. Power reaches the wheels through an automatic gearbox.

The clock stood at 252,423 miles when the data was entered. 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. Services and inspections note the distance covered, so a car with an ordinary past builds up a trail of figures that climb year after year.

No primary damage is given in the record for this car, which is not the same as proof that it has never been damaged. Paint depth, panel gaps and the underbody show whether the body has been repaired.

As a non-runner, the car needs its engine, gearbox and electrics assessed before anything else. The engine started, but that says nothing yet about the gearbox or the drive to the wheels. A key was present.

The record shows a clean title. 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. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

For the engine, the service history matters most: oil changes, filters and the timing belt or chain are the entries to look for. On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. On a car that does not run, the automatic gearbox cannot be judged on the road; the colour and smell of its fluid and a diagnostic scan give the first clues.

A VIN never contains the letters I, O or Q, which could be mistaken for digits; its 17 characters identify the maker, the model and the individual car. The VIN on file for this car is 3GYFNAEY3AS586634. 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. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. 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. For this 2010 Cadillac SRX Luxury Collection, the sensible next step is a history check on VIN 3GYFNAEY3AS586634.
