What is the most popular car in Iowa?

There isn't a definitive, publicly available source that tracks the single most popular car model in each state down to the exact make and model. Data on vehicle registrations is often aggregated at a higher level (e.g., by make, not model).

To find the most popular car in Iowa, you'd need access to Iowa Department of Transportation registration data, which is usually not released in that level of detail to the public. News articles or surveys might offer educated guesses, but they won't be completely accurate.
