million/ US$1.6 million) each. In December 2019, the RHD car sold at a Bonhams auction for £ 575,000 including premium with 2,700 miles. Motorsport Although not intended for motorsport, some privateer teams took it upon themselves to develop the 550 for use in various series. The first racing 550, known as 550 GT, was built for French team Red Racing to comply with international sporting regulations. The project was developed by Michel Enjolras and assembled in the Italtecnica workshop. The car was first tested in April 1999 and was used in the GT3 class of the French FFSA GT Championship. In 2001 the car was then sold to XL Racing who continued the development and built a second car, known as 550 XL entering the FFSA GT and the American Le Mans Series. The older 550 GT also made an appearance at the 2003 24 Hours of Le Mans in the ACO GT class but failed to finish due to technical problems. In 2000, with financial support from some investors led by Stéphane Ratel, Italtecnica created another 550 race car meeting the more powerful GT regulations in the FIA GT Championship, the car being named 550 Millennio. The first car debuted in the 2000 FIA GT Championship, entered by First Racing. The 2001 Championship saw two cars fielded by Team Rafanelli. The 550 Millennio was also developed to meet ACO LM-GTS regulations allowing Rafanelli to enter a single car in the 2002 American Le Mans Series season. In November 2000, German entrepreneur and engineer Franz Wieth launched another racing version of the 550, developed by Baumgartner Sportwagen Technik, and named 550 GTS. Two cars were built, with Wieth Racing entering one in the 2001 FIA GT Championship, then again in 2003, 2004 and 2005. In 2006 the Wieth's Ferrari scored two wins in the Euro GT Series. Commissioned by Frédéric Dor's company Care Racing Development, in 2001 Prodrive built a racing version of the 550 for various sports car series and especially the 24 Hours of Le Mans. Initially known as 550 GTO and then renamed 550 GTS (but not related to Wieth's project), a total of ten cars would be built over the next four years and campaigned by the Prodrive team as well as privateer customers. The cars were entirely built by Prodrive without any support from the Ferrari factory. The factory Prodrive team would win two races
