The follow up model to the 400 GT, the Lamborghini Islero debuted in 1968. Designed by Carrozzeria Marazzi, the Islero was largely a rebody of the 400 GT, albeit with a few small modifications. This similarity often sees the Islero referred to as the 400 GT Islero. While mechanically very similar to its V12 engined predecessor, the Islero added a great deal of comfort to its interior, creating a more refined driving experience. Two versions were built, the Islero Base Model and the Islero S before production ended in 1969 with just 225 examples produced.
