I find myself saying "Porsh-eh" for Porsche (German of course), "sah-oo-nah" for sauna (Finnish), etc.Probably because I'm from a "linguistic minority" (French Québécois, to be precise...), but it matters to me. I think that trying to respect cultural differences (including specifics of language) is a minimum, in a globalized world where the "language of the empire" tends to overtake everything (mind you, I'm not saying that this "language of the empire" is evil, or that it shouldn't be learned; it's what allows me to have discussion with people all over the world).
