2013 MAZDA 3 I VIN JM1BL1U7XD1798875

This Mazda 3 I is a 2013 model. The gearbox is automatic, with front-wheel drive. Power comes from a 2.0-litre petrol engine with four cylinders.

The clock stood at 121,190 miles when the data was entered. The instruments count in miles; the same distance in kilometres is about 1.6 times the figure. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years.

When the car was recorded, it showed side damage. A damage entry is a starting point for the inspection, telling the mechanic where to look first.

When checked, the car could be started and driven under its own power. A key was noted with the car. Months of standing can leave a car with seized brakes and perished tyres.

According to the source data, the car has a salvage title. A title like this is issued when repair was judged uneconomical or unsafe. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title.

Every car builds up a history from the day it is first registered: owners come and go, inspections are passed or failed, and repairs are paid for. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. 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. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. 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.

The tenth character of the VIN stands for the model year, and the eleventh for the plant that built the car. For this car, the VIN is JM1BL1U7XD1798875. 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. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now. A history check on VIN JM1BL1U7XD1798875 is the place to start.
