Cadillac attracted a lot of attention with its Ciel concept, a stunning four-door convertible that was unveiled in August at the Concours d'Elegance classic car show in Pebble Beach, Calif.
But Cadillac isn't the only auto brand eyeing a four-door ragtop.
In case you missed it, a nugget of ragtop news was mentioned in an Automotive News future product story about Mercedes-Benz. My colleague Diana T. Kurylko reported in the Oct. 10 issue that Mercedes may produce a four-door convertible based on the redesigned S class. The next-generation S class sedan arrives in 2013.
