Who sell the most Fords in US?

There isn't a single, publicly available, constantly updated list that shows exactly which dealership sells the most Fords in the US at any given moment. Sales figures are often proprietary information, and rankings fluctuate.

To find out which dealerships sell the most Fords in a particular region or time period, you would need to consult Ford's internal sales data (which they don't release publicly) or look for articles from automotive news sources that may publish such rankings periodically. Even then, the data might be limited and not entirely comprehensive.
