So many people think Mary's body is so blessed that it gives her some special honor and relationship to God. So how blessed is her body due to the simple fact that God used it as a doorway to enter this world?

Christ actually replies to a woman who comes up to Him speaking about how blessed Mary's body is for bearing Him:



However, as you can see, while He DOES agree that it is blessed, He says that RATHER are those blessed that hear the word of God and keep it.

So yes, Mary's body is blessed, but not as blessed as any Christian can be that should "hear the word of God and keep it."
