There's no single answer to the average cost of a new Ford automobile. The price varies dramatically depending on the model (a Ford Mustang is far more expensive than a Ford Fiesta, for example), the trim level (base model vs. high-end), optional features, and the dealership.
To get a current average, you'd need to look at websites that aggregate new car prices, such as Kelley Blue Book (KBB) or Edmunds. Even then, the average they present will be a broad range and may fluctuate.
