* Automotive News: This trade publication often publishes articles and data on vehicle production and sourcing. Their website and archives might contain relevant information.
* Ward's Auto: Similar to Automotive News, Ward's provides industry analysis that may touch upon domestic content.
* The websites of individual car manufacturers: Check the "About Us" or "Company Information" sections of major US automakers (Ford, GM, Stellantis [includes Chrysler, Dodge, Jeep, Ram], Tesla) to see where their vehicles are manufactured. Be aware that some models might be assembled in other countries.
* Consumer Reports: While they don't maintain a specific "American-made" list, their vehicle reviews often mention the origin of manufacturing.
* The American Automobile Labeling Act: This act requires labels showing the country of origin of major vehicle components. You could potentially use this information to infer the level of domestic content in various vehicles, but it's a complex undertaking.
Important Considerations:
* "American-made" is subjective: A car assembled in the US might still use many imported parts. Conversely, a car assembled elsewhere might use a significant number of US-sourced parts.
* Data changes frequently: Manufacturing locations and sourcing change as companies adjust their production strategies. Any list you compile will be a snapshot in time.
In short, creating a comprehensive list requires significant research across multiple sources and involves interpreting potentially ambiguous data on domestic content. The sources above provide the best starting points for your research.
