The Islero was designed by Mario Marazzi, who was working for Carrozzeria Marazzi at the time. Carrozzeria Marazzi was chosen because it was founded by Carlo Marazzi, a former employee of the now-bankrupt Carrozzeria Touring. Carrozzeria Touring had previously produced bodies for the 350 GT and 400 GT.&lt;ref name="qv500.com/lamborghiniislerop1"&gt;&lt;/ref&gt;
