Later cars differed by having recessed and covered headlamps, a closed bonnet bulge, a triangular cutaways in the rear fenders and a lower door line.His owner, Efrain Ruiz Echeverria, traded it in for a new car that was renumbered in the factory to avoid import duty.[8][9] A single example of the Ferrari 340 MM Pinin Farina Berlinetta, that was raced by "Pagnibon", was downgraded to a 250 MM-specification for Andre Vanoni.[3][11] The chassis, reference 250MM53, was made out of a welded steel tubes and featured a 2,400 mm (94.5 in) short wheelbase.The front end had independent, unequal-length wishbones and transverse leaf-springs with Houdaille hydraulic shock absorbers.On the rear end, a live axle with more than traditional semi-elliptic springs and Houdaille hydraulic shock absorbers was mounted.[17][18] Paolo Marzotto and Marino Marini held a third place before their Berlinetta burst into flames a few kilometers before the finish.[19][18] The Portuguese Grand Prix of 1953 brought 1–2 victory by José A. Nogueira Pinto and Casimiro de Oliveira.[25][16] And at the 3rd Annual Madera Road Race, Hill chose a brand new Pinin Farina Berlinetta, that he shared with Bill Devin.[27] The last major race of that year was the 1953 Carrera Panamericana where Ruiz Echeverría and Villegas Becerril finished eleventh overall and seventh in-class.The 250 MM Vignale Spyder, driven by Harry Schell and Alfonso de Portago, arrived at the finish line in second place, also scoring a class win.[29][30] At the Giro di Sicilia, the same year, Vittorio Colocci and Gaetano Spata finished seventh overall and fifth in-class, ironically just behind the 250 S, the predecessor of their model.[32][33] The same year at the Targa Florio, the same 250 MM Morelli finished fifth overall and third in Sport +2.0 class also driven by Biondetti.[13] A very limited production combined with an undisputed racing pedigree, makes for a highly sought after collector's car.[7] Another example, an ex-Phil Hill white berlinetta, was sold for US$7.26 million at the Bonhams, Quail Lodge Auction in 2014.[43] Serial number 0256MM, driven by Eugenio Castellotti to victory in the 10 Hours of Messina, has been owned by collectors in the US, Japan and Germany, before returning to Italy in 2007.
