Yeah I know, there never was a Martini Racing E30 M3, but I love the Martini Racing liveries. So I decided to do a livery for the E30 M3 Gr. A.
It is my first skin / livery for Assetto Corsa, so it may not be perfect.
Extract the martini_racing.rar into "Steam\SteamApps\common\assettocorsa\content\cars\bmw_m3_e30_gra\skins"
