One of the Cadillac custom convertibles made after the last convertible ? I think there was mention special built convertible examples recently. This one on Ebay. Not mine.

No sooner had the dust settled after the "last" convertible sold when coachbuilders began chopping tops off Eldorado Coupes, Coupe deVilles and even a few Sedan deVilles. Hess & Eisenhardt and ACC made the most. ASC joined later and eventually secured the contract to convert the 84 & 85 Biarritz for the factory offering.
Aftermarket convertible conversions never really came to an "official" end. RWD DeVille based convertibles continued well into the 1980s and there have been 1992-2002 gen Eldorado conversions as well.
