From the outside the 58 follows the same creative path as the other semi-enclosed bridge models in the Riviera line. It is not easy penning a good looking convertible that's less than 70 feet without having it appear top-heavy. Riviera's design team has done a good job of diminishing this with a silky smooth unbroken sheer sweep that visually adds to her length. This effect is embellished by the 58's long, slim window line and blacked-out house face. Like her smaller sisters (47E and 51E), her bridge is semi-enclosed with the after end fitted with isinglass. On inclement days one can ride in climate controlled comfort and, if the weather improves, drop the curtains, open the side windows, and retract the electrically operated sunroof. Those that find an enclosed bridge too confining should take a close look at this arrangement because it offers an interesting indoor-outdoor alternative.
