RM Sotheby's Monaco auction will be host to many vintage Ferraris, but one of the showstoppers is this 1957 Ferrari 250 GT Berlinetta Competizione 'Tour de France' by Scaglietti. The car is number 15 of 17 third-series examples with the coveted covered headlights and three louvers and was purchased new by German racing driver Wolfgang Seidel. The Ferrari won a number of competitions including 2nd overall at the 1958 Grand Prix Spa-Francorchamps. The car features fully matching numbers and is Ferrari Classiche certified. The car has seen only a handful of owners in its lifetime and the current owner has had the car since 1997.
