A very rare 'bird indeed. Weathered condition aside, this really is quite a Thunderbird. 1971 was the last year for the 4-door Thunderbird and the factory power sunroof was an expensive and very scare option. http://sacramento.craigslist.org/cto/5067954241.html
Definitely not my favorite years for the T-Bird. This body style and the 1980-1982 FOX cars are at the bottom of my list. At least the 1967-1969 cars incorporated an extra set of doors and still looked cool. But the Bunkie Knudsen front ends kills these cars.
I respectfully disagree about the design. The Bunkie "beak" front prow did not serve the 4-doors well, I will acknowledge, but for the 2-doors along with the new-for-1970 fastback roof line, I think it looks awesome! Motor Trend did a comparison article for 1970 of personal luxury coupes including Grand Prix and the brand new Monte Carlo and put the T-Bird on top.
I owned a '69 4-door Thunderbird for a while. A great cruiser, but not so awesome in the 'cost-of-ownership' column when it's the middle of the first gas crisis and you're only making a few hundred a month......
