2016 MAZDA MAZDA6 I GRAND TOURING VIN JM1GJ1W52G1482057

This record covers a 2016 Mazda MAZDA6 I Grand Touring, finished in black. The gearbox is automatic, with front-wheel drive. Under the bonnet is a 2.5-litre petrol engine. The specification is taken from the source data and has not been checked against other documents.

The clock stood at 325,457 miles when the data was entered. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. The mileage is high for the car’s age, so the suspension, brakes, seats and steering wheel deserve a close look. 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.

No damage type appears in the source data; that shows what was entered, not what the car has been through. Signs of an old repair – uneven panel gaps, overspray, a slight mismatch in paint – can still turn up at an inspection.

A key was noted with the car. Months of standing can leave a car with seized brakes and perished tyres.

A clean title is on file for this car. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

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. 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. 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 ninth character of the VIN is a check digit calculated from the other sixteen, so a mistyped or invented number does not add up. The VIN on file for this car is JM1GJ1W52G1482057. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. The past is on file; the car’s condition today is a job for a mechanic, who can check the structure, underbody, electrics and any repairs on a lift.
