A growing number of automobiles in Arizona are electric vehicles, or EVs, with sales having increased significantly in recent years — and one Ford auto dealership in the Phoenix area set a U.S. record for selling more electric vehicles than any other dealership.

He and others suggest certain strategies for prospective auto buyers in ensuring their new car purchases turn out to be smart choices.
