Drophead coupé.

Full-house DS converted by Chapron, quoted in UK 1963-68 only. Over the years, too, cabrios are also made to ID spec. From 1966 model-year only with DS21 2.2-litre short-stroke engine; swiveling head-lamps for 1968. Later ones have fuel injection and option of five-speed gear box. All the complexity plus the structural headaches of a unitary top-chop. You'll be lucky to find one.
