A Trofeo racing series was organized for enthusiasts, with a per-race rental charge of about US$20,000. For the 2005 season of the race, the Coupé-based Trofeo was updated and since based on GranSport model. A Trofeo Light (or simply the Maserati Light) was also developed for use in various national and international racing series, including the Italian GT Championship, Rolex Sports Car Series, and FIA GT3 European Championship. It is distinguishable from the Trofeo by having a wider flared wheel-arches with air-exhaust behind front wheels and wider rear spoiler. Special editions The Maserati Coupé and Spyder special editions are primarily exterior trim packages that were only offered for certain model years or on a limited number of vehicles. They include: 2004 'Spyder 90th Anniversary' GranSport 'Limited Edition' 2006 GranSport 'MC Victory' 2006 GranSport 'Contemporary Classic' 2007 GranSport 'Maserati and Cornes 10th Anniversary' Also, in 2004, a Vintage trim package was introduced. It includes chrome air-exhaust vents in the front fenders, a new polished wheel design, silver-finished brake calipers, and chrome door handles. The front fender vents were intended to evoke those of the 1957 3500 GT. A 2004 Coupé 90th Anniversary edition was announced, but apparently never produced. The 'Spyder 90th Anniversary' was shown in late 2004 and produced in the limited number of 90 cars for North America and another 90 cars for the rest of the world. 15 were in right-hand drive, mainly for Britain. This edition is not a GranSport but a regular Spyder model that is visually based on the GranSport bodykit (without power upgrades), and may be recognised by its oval Maserati badges on the front fenders, titanium coloured brake calipers, grey headlamp housings and a special blue/grey interior with limited edition plaque. The headrests also received aerodynamic fairings behind the rollover bars. Special Blu Anniversary paint could be chosen. The 'MC Victory' edition features details made out of carbon fibre like: front splitter, racing seats and rear nolder. Centre console bears the limited edition plaque and there are Italian flag emblems embedded into front fenders. Most cars were chosen in exclusive Blu Victory paint. It was unveiled at the 2006 Geneva Motor Show to celebrate the racing success of the MC12 GT1. Only 181 cars were made. A 'Limited Edition', destined for US market is recognizable for the “Saetta” logo featuring the Trident with red accents and oval Maserati badges on front fenders. The
