The special Presidential convertibles get an updating

For 10 successive years United States Presidents have used the same two convertible limousines in official functions and parades. Now, at long last, Lyndon Johnson has a brace of spanking-new replacements. Lincoln Continentals, they have 11-inch-wide running boards, plus a retractable rear platform of equal width, for Secret Service men. A hand bar can be recessed flush with the trunk lid. The rear doors of the four-door cars are in two sections to allow agents a 15-inch walk-through. A transparent top permits surveillance of rooftops and other elevated structures.
