The long-wheelbase Fleetwoods came with everything found on deVilles (except front center arm rest in the limousine) plus Automatic Level Control; Automatic Climate Control; rear window defogger; four rear ash trays; and a manual righthand outside rear view mirror. Externally, they had the new Cadillac styling and window treatments similar to those described for the Sixty-Special. However, the rear roof pillar could be custom finished in several different ways, including triangular "coach" windows or vinyl covered "blind quarter" looks. Ornamentation included the traditional Fleetwood laurel wreath crests and lettering, plus thin horizontal belt moldings. However, no rocker sill strips, panels or extension moldings were used. And, of course, the limousine had the doors cut into the roof, special upholstery appointments and a driver's partition with adjustable division window.
