2012 VOLKSWAGEN JETTA 2.5L SE VIN 3VWDX7AJ3CM370659

The Volkswagen Jetta 2.5L SE described here left the factory in 2012. The engine is a 2.5-litre petrol unit with five cylinders. The gearbox is automatic.

The clock stood at 172,313 miles when the data was entered. 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. 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 damage to the right front. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Whatever the cause, a diagnostic scan of the car’s electronics shows fault codes that a visual check misses.

A ‘runs and drives’ note means the car moved under its own power when it was checked. A key was there when the car was checked. Condition notes are a snapshot: the car may have been worked on, stripped of parts or left standing since.

The car carries a salvage title. Titles of this type are issued to cars declared a total loss. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. A clean, polished car can still hide a serious accident, a flood or years of hard use.

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. On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. 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. The VIN 3VWDX7AJ3CM370659 belongs to this 2012 Volkswagen Jetta 2.5L SE. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

A VIN report gathers what different sources know about a car, such as the number of owners, mileage readings, damage and any branded title. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. 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. Before going any further with this Volkswagen Jetta 2.5L SE, it makes sense to look up VIN 3VWDX7AJ3CM370659.
