I'm about 5'6" and the first thing I noticed when looking in the rearview mirror is that if someone pulls up to you at a stoplight, it is harder to see as much of their car as I am used to seeing in my '95 T/A ragtop. The top on the T/A sits flush with the trunk lid, whereas the Mustang doesn't go down nearly as far. I wish it did, but after driving it all last summer I just got used to it. It is hard to tell from the angle of the pictures you took, but it does seem that yours looks different than mine when down.
