2015 BMW ALPINA B6 VIN WBA6B4C51FD760553

The BMW Alpina B6 described here left the factory in 2015. The gearbox is automatic, with all-wheel drive. The engine is a 4.4-litre petrol unit with eight cylinders. The specification is taken from the source data and has not been checked against other documents.

The clock stood at 110,965 miles when the data was entered. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. 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.

When the car was recorded, it showed front-end damage. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since.

As a non-runner, the car needs its engine, gearbox and electrics assessed before anything else. The engine could be started. A key is on file for the car. 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.

According to the source data, the car has a salvage title. At some point in its life, the car was declared a total loss.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. Pieces of a car’s history sit with registries, dealers, workshops and insurance companies, and none of them sees the whole picture. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

When a car does not run, a compression test and the condition of the oil tell a mechanic whether the engine can be brought back to life. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. With no test drive possible, the automatic gearbox has to be assessed on a lift and with diagnostic equipment. With all-wheel drive, mismatched tyres can strain the centre differential or coupling, so all four should be the same make and similarly worn.

A vehicle identification number has 17 characters: the first three name the manufacturer, the next six describe the model and its specification, and the last eight identify the individual car. The record gives the VIN as WBA6B4C51FD760553. 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.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. 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 WBA6B4C51FD760553 first, and let what it shows guide the inspection.
