I guess everyone has their own interpretations to what bodies are or should be legal as the rules are left pretty open. What I like is that there is a good variety of bodies that people use. Being a motorsport fan myself, I interpret the rules specifically to GT racing. I try to use bodies that have or currently compete in sanctioned GT series: GT300/GT500, GT Lemans, DTM, FIA GT3, Blancpain, etc. At the same time encouraging race liveries and discouraging prototype (i.e Daytona Prototypes/LMP1) and non GT cars. Just my opinion.
