Less headroom?

Is there less headroom in the 2004 and up
Grand Prixs? Im 6'0 ft. and I sat in a 2005
GP and its seems the headroom is less.
My 2002 seems like it has more headroom.

Here is a side by side comparison of interior space. They are pretty similar.

They are suppose to be simular but my friends mother has an 07 gp and it seems to be less headroom but I think its because the seats are bigger than the 97-03 gps.

Didn't palsut do an 04 seat conversion? I wonder if it changed the headroom is his car...
