Does anyone feel the same like me?
Every time I am in my 911 -991.1 I just found out that the seat is too high and sometimes might impact my viewing from the mirror (I will see the co-pilot seat on mirror)!

And what's more , sometimes I place something behind or it's raining, the rear mirror even comes useless cuz I can't see anything from my rear................

 

Try adjusting your rear view mirror? I'm not sure I understand the question.
