Typically, none of the 36 GTOs made in the first 1962-’64 production run were identical. Although the bodies were all hand-beaten in aluminium over wooden bucks by Scaglietti’s artisans, there were many differences, some cosmetic, others more empirical and engineering-focused. Indeed, as with many historic Ferrari models, you need to be a mix of Indiana Jones and Hercule Poirot to figure out what was really what. The first 18 cars were supplied with the rear spoiler as a separate item, which then had to be bolted to the body. One of the 36-strong production run had a completely different body design, mirroring the 330 LMB. Variations included the rear wing, the size of the radiators, the number of ducts, and various other amendments.
