- Confirmed at quotation
We do not infer emissions eligibility from a model designation. Where a value reads “not recorded” or “not evaluated”, we hold no documented evidence for that configuration and will confirm it before quoting. An international-specification engine is not a United States-specification engine, and a United States-specification engine is not automatically California eligible.
