[database] Dataset - Vehicle make/model/year (free)

I am creating an app that needs all available US automotive make/models for each year. I have read several suggestions on other posts, like use Freebase or DbPedia or EPA, but those datasets all appear rather incomplete and inconsistent. I checked out open APIs like Edmond's, but they restrict storing their data - I need it in my db, so that doesn't work. Any suggestions where I can get this data without having to shell out money?

This question is related to database

The answer is


How about Freebase? I think they have an API available, too.

These guys have an API that will give the results. It's also free to use.

Note: they also provide data source download in xls or sql format at a premium price. but these data also provides technical specifications for all the make model and trim options.
