Canadian-market vehicle dimensions and weights from NHTSA vPIC's Canadian Vehicle Specifications dataset. Pass year + make (required) and optional model to narrow. Returns one entry per matching trim with labeled dimensions — overall length/width/height (cm), wheelbase (cm), curb weight (kg), front/rear track width, interior head/leg/shoulder/hip room, and weight distribution — plus the full raw spec map. Authoritative measured specs (the SAE dimension codes), not estimates. Keyless, public-domain; covers model years 1971+.
