The Lamborghini 350 GTS was the open-top version of the 350 GT, first shown in 1965. It retained the same 3.5-liter V12 and overall mechanical layout as the coupe, but featured a removable roof panel, giving it a more relaxed grand touring character. Only two examples were built, making it one of the rarest early production Lamborghinis. Despite the appeal of a convertible V12 Lamborghini in the mid-1960s, the model never went into full production, likely due to limited demand and the company’s focus on developing newer models like the upcoming Miura.
