Eleanor was the code name for a 1967 Shelby Mustang GT500 in the gear head movie Gone in Sixty Seconds in the summer of 2000. Shelby never made an Eleanor and neither did Ford. The movie cars were not Shelby Mustangs. The car used for the sound effects of Eleanor was an original 1967 GT 500. Eleanor was built from 1967 Mustangs with modifications.
Shelby Mustangs are very rare cars, a real unmodified Shelby GT500 can range from $100,000 to $190,000+ but the good news is that you can buy or build an Eleanor looking car for $60,000 to $250,000 depending on what you want.
Jerry Bruckheimer retained one authentic Eleanor, outfitted to resemble the movie's car, for his own use. The other twelve vehicles were customized 1967/68 Mustangs. One was chopped up for camera work. Two were destroyed for The Jump along with others for the scene at Calitri's wrecking yard. Seven Eleanor's survived. Some were modified for high-speed driving, others for sharp turns. Engines ranged from stock 289 to crated 351s. Keep in mind the actual GT 500 used the Ford big-block 428 cid mill which produced an advertised 355 horsepower.
So unless your Jerry Bruckheimer you don't
