2008 BMW 335 I VIN WBAVB73558P102572

The BMW 335 I described here left the factory in 2008. The engine is a 3.0-litre petrol unit with six cylinders. The gearbox is automatic, with rear-wheel drive.

The clock stood at 103,029 miles when the data was entered. Miles and kilometres are easy to confuse, and a distance in miles looks lower than the same distance in kilometres. Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

In the source data, the main issue is front-end damage. The damage type is a short label: the extent of the damage and the quality of any repair still have to be judged on the car. 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 present. A condition note describes the car at one moment; months of standing or later work on the car can change the picture in either direction.

The record shows a salvage title. A title like this is issued when repair was judged uneconomical or unsafe.

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.

Regular oil changes and timely work on the timing belt or chain decide how well an engine copes with age. A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was.

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 WBAVB73558P102572. The number in the car’s documents should match the one stamped into the body and the one on the plate at the base of the windscreen.

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 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.
