2009 CADILLAC CTS RWD W/1SA VIN 1G6DF577690146693

This record covers a 2009 Cadillac CTS RWD. The petrol engine has six cylinders. There is an automatic gearbox, with rear-wheel drive.

The recorded mileage is 159,927 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. 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.

When the car was recorded, it showed damage to the left side. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. Damage rarely stays where it is first seen: an impact can reach the mountings and airbags behind a panel, and water or fire the wiring and electronics.

When checked, the car could be started and driven under its own power. A key was present.

Title status in the record: salvage. A title of this kind usually means the car was written off as a total loss after damage. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title.

A car’s history is everything logged against it since it left the factory: registrations and owners, inspections, repairs and insurance claims. From the outside, a car with a repaired accident and a car without one can look identical.

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. A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was.

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 1G6DF577690146693. The number in the car’s documents should match the one stamped into the body and the one on the plate at the base of the windscreen.

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. A history check on VIN 1G6DF577690146693 is the place to start.
