1971 Mercury Cougar XR7 convertible with 4 speed ram air 1 of 1 according to Marti report. Original color is medium brown metallic. Very nice driver quality. I have owned 6 429 CJ Cougars this one is nice. Only 6 429 CJ XR7's J code known left. This is very unique car. Most people have never seen one. You will love the expression from people once they see the engine. According to the Cougar Club of America only "448 429 Cougars were built 47 were convertibles and 401 hardtops". Check out CCOA website and look for 429-cj htmIf you have any questions let me know 3176253150.
