High Quality Content by WIKIPEDIA articles! The Panther Rio was a motor car made by British manufacturer Panther Westwinds, using Triumph Dolomite mechanicals. According to the company, it differed from the family saloon-class Dolomite, in being finished to "Rolls-Royce standards". Only 38 were built between 1975 and 1977. A rarer Rio Especial used the high-performance Triumph Dolomite Sprint as its basis.
