1971 Mercury Cougar convertible - only 1,722 convertibles ever produced , with this particular one being .... ONE OF ONE ! Kind of like Tigger , it's the only one !! According to the Marti Report , this Cougar is the only one ever built with this equipment and color combination . It has the Cleveland 351 4bbl V-8 engine , the C6 transmission , air conditioning , am radio with an 8 track player and tilt column . It is Pastel Blue , code 921-A , with the White Knitted Vinyl bucket seats , code 5W , and a white power convertible top . The Styled Steel Wheels completed it's singularity of the 3 that were ever built with this color combination . Lady owned , who purchased it from the original owner , always garage kept , this trophy winning Cougar shows 58,800 miles , reported as actual to me , it runs and drives great , still shows very well and would enhance anyone's collection . First place trophy for "TOP CAT AWARD" at the 2016 Western Regional Cougar Club of America's show in Oakley California , second place overall finish . One repaint to the original Pastel Blue some 20 years ago combined with original interior and factory equipment makes this beauty an absolute survivor !!
