2015 BMW 320 I XDRI VIN WBA3B5G54FNS19221

This BMW 320 I Xdri was built in 2015. The gearbox is automatic. The engine is a 2.0-litre petrol unit with four cylinders. The specification is taken from the source data and has not been checked against other documents.

At the time of recording, the car had covered 77,860 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. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

The record lists front-end damage as the main problem on this car. Whether the damage has been repaired since, and how well, is not something a damage entry can show. A lift and a diagnostic check show what photos cannot: bent brackets behind a panel, chafed wiring or deployed airbags.

No key is recorded with the car, and a replacement has to be coded to the immobiliser. Running condition describes a single moment, and standing or work done since can change it.

The car carries 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, however sound the car looks.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

For the engine, the service history matters most: oil changes, filters and the timing belt or chain are the entries to look for. On a petrol engine, a rough idle, misfires or a warning light on the dashboard need looking into. 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. A car with all-wheel drive has extra differentials and often a transfer case, which an inspection should cover alongside the engine and gearbox.

The tenth character of the VIN stands for the model year, and the eleventh for the plant that built the car. This car’s identification number is WBA3B5G54FNS19221. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

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. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. The next step is to look up the history behind VIN WBA3B5G54FNS19221.
