1961 Ford Thunderbird Convertible

For 1961, the Thunderbird was changed from "stem to stern", including a brand-new 390-cubic inch, 300-horsepower engine which was standard equipment. The convertible top operation was again automatic, and again, unlike the Lincoln Continental, it required manual release of the windshield mounts before the top could be lowered.

From the 1961 Ford Thunderbird brochure:

"The most beautiful convertible ever built!" "Without leaving the driver's seat you snap open the top clamps, push the top control switch and at once the rear deck starts to rise."  "...with the top neatly stowed away the rear deck lid closes itself. There's not a hint that this car ever had a roof."
