After the success of the Sprint Veloce, Alfa Romeo decided to build a small number of lightweight, purpose-built competition cars based on the Giulietta Series platform in 1959. Zagato was enlisted to build an aero dynamic, full-aluminum body. The windows were of plexiglass and a special lightweight interior was designed – all to save weight. The inline four-cylinder engine had a special build, Weber carburetors, air intake, and the best tuning to get the maximum horsepower. Special three-shoe drum brakes and light alloy wheels. Known as the SZ1 or Sprint Zagato Coda Rotonda (Round Tail). Just over 160 cars were built.
This car was completed on January 26, 1961 and was supplied new to Libero Liberati, then 34, in Terni, Italy on April 27, 1961. He was the 1957 Grand Prix World Champion for 500cc motorcycles, besting famous riders John Surtees and Geoff Duke. This SZ was his race car until his death in 1962. It is believed that this SZ was a Scuderia Ambrosiana car of Liberati with Carlo Facetti as tuner. During the 1980s, the car was purchased by Martin Swig out of the Netherlands. Swig, a California collector and motoring enthusiast loved Alfa Romeos. He started the California Mille and became a major influence on the use and enjoyment of Mille Miglia eligible cars.
Martin Swig sold the car to Stephen Barney of Foreign Cars Italia (Greensboro, N.C.) in 1990. Since 1997, the car belongs to a long-term Alfa enthusiast with several historically significant vintage Alfa Romeos. The restoration, completed in 2005, warranted a place in the Pebble Beach Concours d’ Elegance (2005), where it was first shown, as well as several other concours. It was then actively campaigned in vintage racing events on the east and west coasts, including the Monterey Historics in 2009, 2012, 2014 and 2015, the Rolex Vintage Festival, Lime Rock Park in 2007 and 2008, the Portland Historics in 2009, at CSRG Sonoma in 2011, among other historic events.
