Porsche
What is the correct pronunciation of Porsche? While the “proper” way to pronounce some German terms in English may be debatable, this isn't one of them. Porsche is a family name, and the family members pronounce their surname PORSH-uh, not PORSH! Same for the car. You don't say NYKE for Nike, so don't be lazy and leave off the e in Porsche! Porsche's U.S. TV commercials pronounce the name correctly and so should you.
So 1=B
as for the struts:
I believe that Boge is a German brand, If I'm correct about this then I think The letter G should be pronounced like the letter X in Mexico (when said in Spanish), it is not exactly the same but I don't no any English words with a "soft" G. Other, smarter people, please chime in.
Again B (closest)
Fuchs: CH to be pronounced in a similar way as the G in Boge (maybe a bit "harder"
Closest is B but not pronounced as a K, more like the G from Boge
Please do not use FEW-KS, it sounds horrible (and I'm not even German)
Isn't K9handler German?? He should know this then
