2014 CHEVROLET IMPALA 2LZ VIN 1G1155S39EU172353

The Chevrolet Impala 2LZ described here left the factory in 2014. Power reaches the wheels through an automatic gearbox. Power comes from a 3.6-litre petrol engine with six cylinders, rated at 305 hp. Details for this car come from a single data source and may differ from its documents.

The record gives the mileage as 269,526 miles. Miles and kilometres are easy to confuse, and a distance in miles looks lower than the same distance in kilometres. High mileage alone does not rule a car out; what matters is whether regular servicing kept pace with it. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

The record lists front-end damage as the main problem on this car. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since. Given the kind of damage entered, a mechanic should look first at the radiator support, the headlamp mountings and the front crash structure.

A note in the source data says the car did not run. An engine that will not start could have a simple electrical fault or internal damage, and only diagnostic work can tell which. No key was present. Running condition describes a single moment, and standing or work done since can change it.

According to the source data, the car has a non-repairable title. At some point in its life, the car was declared a total loss. If any work has been done on the car since, photos and invoices should show what was replaced.

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. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

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 record gives the VIN as 1G1155S39EU172353. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. 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 1G1155S39EU172353 first, and let what it shows guide the inspection.
