Zitat von n1Co

Sorry, but unfortunately it was before I was born...
And why do you want to know that ?

Thank You, n1Co, at least to say something !
This work I've been doing for a very long time it's to complete the much as I can the data concerning all the drivers that have participated in the WRC. I know that most of F1 statistics are complete (ok, 20-30 drivers per race, instead of 100-300 in a rally) so why not those from WRC ?

best regards from Portugal
Happy New Year for all the forumers
