On October 28, 2009, Zagato and Ferrari announced the 550 GTZ Barchetta – an open version of the 575 GTZ coupé, built to mark 90 years of collaboration between the two companies. Unlike the coupé, it is based not on the 575 but on the older 550 Barchetta Pininfarina. Only three cars were built, one of them with right-hand drive. In contrast to the original, Zagato developed an electrically operated soft top. The design was inspired by the 250 GT Berlinetta of 1956. Each car cost 1 million pounds; the right-hand-drive example was sold at a Bonhams auction in December 2019 for 575,000 pounds.
