About Fabian Kreim: he has the luck Skoda Germany invest a lot in him; he drives in 2016 the German championship, the Asian-Pacific rounds, already 2 rounds in Czech from one of them was the Barum ERC round and also the German WRC round. And when the competition is strong (WRC & ERC) you can clearly see he has still a long way to go to reach the top.
Skoda gives him also a semi-factory car and that's why he's a bit faster (on the straights) against a privat driver like Riedemann. I think Riedemann (and Aaron Burkhart) are the most talented drivers in Germany. Sepp Wiegand was also nothing special, like Kreim a lot of rally's and support but in the end it was clear he wouldn't make it to the (even the ERC) top.
