Actually, after the ban of the cars, the manufacturers looked for other races where they could use their monsters. They took them to Dakar, and to the famous Pikes Peak hillclimb race in the USA. Peugeot made a very good movie about it (although it is in a 405T16, which technically never raced group B, the car is basically a 205 T16 with another body shell) - https://www.youtube.com/watch?v=UEuZG37gFdM
