This makes this great car eligible to participate at the most selected and prestigious event.
This specific car got manufactured in 1951, being one of the earliest series. It spent 22 years at the ministry of defense before it got sold on 10/10/1973 to a civil private owner called Signor Luigino Pollesel of Tarzo-Treviso (Italy). Sig. Pollesel used it for 15 years. His son Oddone still remembers to have learned how to drive with this car. Then Sig. Pollisel sold it to Da Re Tranquillo of Fregona (Treviso) on 19/08/1998. On 25/07/2001 it got sold to Sig Claudio Dall’Antonia of San Pietro di Feletto (Treviso) who right after sold to Autieri (Associazione Nazionale Autieri d’Italia) and “Museo storico della motorizzazione” at Prato-Italy. This military museum sold it on 25/09/2003 to Signor Vito Oliva. Sig. Oliva used it as it was for several years and registered it on 25/10/2007 at the A.S.I. (Automoclub Storico Italiano) proving the total originality of the car. In 2004 Sig. Oliva started a frame offnut and bolt restoration of the AR51 and drove it very little in Italy until 21/01/2015 when it got exported to a car german dealer. It was never registered there and it got purchased a few months later by our company in August 2015 and then exported to Spain.
