this sounds wierd to me. I have heard vaz that does not really rhyme well with anything but is close to cause from because or like saws or laws. Never as something that rymes with mars or cars though. And the vase as in face type I have heard to.
Really? What reason could stand at the base of of your pronunciation? Can you provide even a single case where someone would lose face to embrace pronouncing it with such disgrace? I have half a mind to chase you away from this place. Or at the very least replace or erase you from this sharing space.
