Ford is offering its dealers to invest up to $1.2 million to start selling electric cars. About 90 percent of that amount will go toward installing charging stations. Dealers have until Oct. 31 to make a decision and have until the end of the year to make the investment. Company expects the investment, and the specialization of smaller dealers in certain vehicle categories, will reduce the cost per car sold by $2,000 to compete with the direct-to-consumer sales model used by Tesla and other startups.
