2008 MAZDA CX-9 VIN JM3TB28A580155081

This entry is for a 2008 Mazda CX-9, finished in black. Power comes from a 3.7-litre petrol engine with six cylinders. Power reaches the wheels through an automatic gearbox. Every figure for this car is given as it appears in the source data.

At the time of recording, the car had covered 248,949 miles. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. The number on the clock proves little by itself; earlier figures logged at services and inspections are what make it believable. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

The record lists side damage as the main problem on this car. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. With side damage on file, the inspection should start with the door pillars, the sills and the side airbags.

The record notes that the car ran and drove. A key is on file for the car.

The car carries a salvage title. A title of this kind usually means the car was written off as a total loss after damage. A branded title follows the car through every change of owner, so it remains part of its history.

A car’s history is everything logged against it since it left the factory: registrations and owners, inspections, repairs and insurance claims. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. 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. 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 record gives the VIN as JM3TB28A580155081. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. The absence of an entry is not proof that nothing happened; it may only mean that nobody wrote it down. 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 JM3TB28A580155081 first, and let what it shows guide the inspection.
