2016 MAZDA 3 SPORT VIN JM1BM1U78G1338132

This entry is for a 2016 Mazda 3 Sport, finished in grey. Power comes from a 2.0-litre petrol engine with four cylinders. The gearbox is automatic, with front-wheel drive. The specification is taken from the source data.

The record gives the mileage as 168,345 miles. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. 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. Gaps of several years between logged figures deserve attention, as does any reading lower than the one before it. 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 front-end damage. Whether the damage has been repaired since, and how well, is not something a damage entry can show. Whatever the cause, a diagnostic scan of the car’s electronics shows fault codes that a visual check misses.

When checked, the car could be started and driven under its own power. A key was there when the car was checked. 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 of this kind usually means the car was written off as a total loss after damage. If any work has been done on the car since, photos and invoices should show what was replaced.

A car’s history is everything logged against it since it left the factory: registrations and owners, inspections, repairs and insurance claims. Pieces of a car’s history sit with registries, dealers, workshops and insurance companies, and none of them sees the whole picture. From the outside, a car with a repaired accident and a car without one can look identical.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating.

A history check works by VIN because the number never changes, unlike registration plates and owners. The VIN on file for this car is JM1BM1U78G1338132. 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. 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.
