Help with question word だれ


Every example I see with だれ and a copula has だれ placed at the end (あの方はだれですか。)
Will changing the order to だれがあの方ですか。be acceptable or mean something else?

Also, how do I write "Who has A car?" I want to say だれがくるまがありますか but it looks
odd having 2 が particles.




I am a native Japanese speaker who has lived in Japan for 27 years but I have
never heard anyone say だれがあの方ですか. Let's say you and your listener have talked
about a specific person "A" before, and there are many people in front of you
including the person "A." You want to know which one is A, and then maybe you
would say だれが"あの方"ですか, referring to the person A(=あの方)? In that case,
だれが例の方ですか is usually used though.

Whenever you are pointing one person and want to know who that person is, just
use あの方はだれですか.
