(2) Obtain motor vehicles that achieve maximum fuel efficiency;

(3) Limit motor vehicle body size, engine size and optional equipment to what is essential to meet the agency's mission;

(4) With the exception of motor vehicles used by the President and Vice President and motor vehicles for security and highly essential needs, obtain midsize or smaller sedans; and

(5) Obtain large sedans only when such motor vehicles are essential to the agency's mission.
