2014 CADILLAC ATS LUXURY VIN 1G6AH5RX6E0176717

The Cadillac ATS Luxury described here left the factory in 2014. Power comes from a 2.0-litre petrol engine with four cylinders. There is an automatic gearbox, with all-wheel drive. Details for this car come from a single data source and may differ from its documents.

Gaps of several years between logged figures deserve attention, as does any reading lower than the one before it. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

Primary damage in the record: front end. A damage entry is a starting point for the inspection, telling the mechanic where to look first. Some damage shows its consequences only later: corroded connectors and electrical faults can surface months afterwards.

A key was there when the car was checked. Running condition describes a single moment, and standing or work done since can change it.

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.

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. 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.

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. 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. A car with all-wheel drive has extra differentials and often a transfer case, which an inspection should cover alongside the engine and gearbox.

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. The VIN on file for this car is 1G6AH5RX6E0176717. 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.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. Paperwork is only as complete as the people who kept it, so a report with few entries lowers the risk without removing it. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. Look up the history of VIN 1G6AH5RX6E0176717 first, and let what it shows guide the inspection.
