Every specification on ownerspecs is checked against a primary document: an owner’s manual, a professional workshop dataset, a national vehicle registry, a Certificate of Conformity, or a first-party photograph of the car’s own door-pillar placard and type plate. That verified data is published here as a free, machine-readable dataset so anyone can build on it.
