"Are we taking my car or yours?"
Translation:¿Cogemos mi carro o el tuyo?
is there a problem that I'm missing with "estámos tomando mi coche o tuyo?"
I don't think so. Should be accepted. Except perhaps that in referring to someone else's car I think you need to say "el tuyo".
I've lost my patience! I put "Estamos tomando mi coche o el tuyo" and got it wrong. I REALLY want to know why this is wrong?! What am I missing?
