A diesel M Sport wagon already has a distinct brief, and this example adds a KermaTDI tune, Apex wheels and a CarPlay retrofit. The appeal is a long-distance wagon with specific enthusiast changes rather than a generic used 3 Series. Those changes also create questions: the calibration, emissions hardware and quality of the retrofit all need documentation. We selected it for its configuration, with the asking price best assessed alongside the service file at just over 100,000 listed miles.
