Having competed in 2 World Championship Rallies in 1982 and 1986, I can say that there is a heap of difference between a tarmac spec rally car, a gravel spec rally car, and a snow spec rally car.
The Europa, like a Clan Crusader, a Renault Alpine A110, and a Darrian, are quite suitable as tarmac spec rally cars. I have even seen Ferrari 308s used. The A110 is one of my favourites along with a Metro 6R4 (which I had), and a Lancia Stratos (which is far too expensive).
