At the end of 2005, the newly formed Super Aguri F1 team took over the ex-Arrows base at Leafield in Oxfordshire and bought four unmodified Arrows A23's from Minardi, all of the spare parts, as well as the Arrows Grand Prix International intellectual property rights. Many of the ex-Arrows staff was hired to engineer the team, including technical director Mark Preston. The 2002 Arrows A23's were run (with minor modifications) as the Super Aguri SA05 during the first races of the 2006 season. An update of the 2002 Arrows chassis was designated the SA06 and made its debut at the 2006 German Grand Prix.
