The Lamborghini 3500 GTZ was a rare and short-lived experiment from 1965, created as a more aggressively styled alternative to the 350 GT. Built by Carrozzeria Zagato, only two examples were produced. Compared to the elegant Touring-bodied 350 GT, the 3500 GTZ featured sharper lines, a more compact fastback profile, and Zagato’s distinctive lightweight approach. Despite its striking design and exclusivity, it never entered series production, making it one of the earliest and most unusual coachbuilt Lamborghinis.
