2015 CHEVROLET TRAX 1LT VIN KL7CJRSB7FB135984

The Chevrolet Trax 1LT described here left the factory in 2015. Under the bonnet is a 1.4-litre petrol engine. The gearbox is automatic.

At the time of recording, the car had covered 171,624 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. Averaged over the car’s age, the mileage works out well above the usual annual distance, and wear on the suspension, brakes and interior should be judged with that in mind. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

In the source data, the main issue is front-end damage. Whether the damage has been repaired since, and how well, is not something a damage entry can show. 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.

The record notes that the car ran and drove. A key was noted with the car. Months of standing can leave a car with seized brakes and perished tyres.

Title status in the record: clean. With a clean title the car can be registered and insured in the usual way.

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. 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, a rough idle, misfires or a warning light on the dashboard need looking into. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating. Drive to all four wheels means more to maintain: differentials and couplings have oil of their own, which some manufacturers want changed at set intervals.

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 KL7CJRSB7FB135984. 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.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. Before any decision, check what is known about VIN KL7CJRSB7FB135984.
