Starting from the base of the 365 GT4 / BB of 1973, in 1976 the 4943cc 12-cylinder boxer was used for the 512BB, which took up the shape of the 365, with some differences in details, such as the front spoiler, two NACA vents on the sides and circular rear lights with two instead of three elements. The 512BB had 4 Weber 40UCF3C carburettors, which were replaced in 1981 by Bosch K-Jetronic injection on the 512BBi model. The BB immediately became a very coveted car and certainly one of the most fascinating road Ferraris ever, for its line and the high performances.
The Italian Best was founded in 1990 as one of the successors of Box Model. The Box Model molds were split between Best and another Italian company, Bang. Best, directed by Marco Grassini with the company called M4 (named after the founder and his family: Marco, Mariella, Michele and Manuela), thus began producing high quality die-cast models in 1:43 scale. The quality has increased over time, especially thanks to the use of photo-etched parts. The company produces sports and racing car models from the 60s and 70s, mainly Ferrari, but also Alfa Romeo, Lancia, Porsche, Jaguar and Lola. The owners of Best also produced the Art Model (Ferrari, since 1993) and M4 (Alfa Romeo models, since 2007) brand ranges, and in 2004 they took over Rio material. After the death of Marco Grassini in 2016, the business is carried on by his family.
