This page is about a model, not a car
Two 2011 BMW Z4s can have entirely different histories, and a recall campaign usually covers a build-date window rather than a whole model year — which a VIN does not encode, so only the door-jamb label settles it. Scanning the VIN adds the decode, the crash tests, the fuel economy and the complaints matched to that exact engine, trim and assembly plant.
