So big glass roof panels are not all that special these days--though they are nice. But big glass roof panels that move this elegantly are few, indeed, and this one you'll find on the 2013 Lincoln MKZ.

The video, released today by Lincoln, shows the retractable glass roof in action, gliding silkily open and closed. It even moves on its own, sliding forward eight inches at speeds over 40 mph to minimize wind noise and turbulence in the cabin.

While we'll have to test it ourselves before we issue a final verdict, we have to admit, it looks slick in the video. Hopefully we'll get a closer look when it makes its production debut at the 2012 New York Auto Show next week.

What do you think? Is this feature of the 2013 MKZ enough to sway you toward considering it over the alternatives? Or does the baleen-whale grille and Lincoln image still put you off? Did it ever?

Let us know your thoughts on the issues--or successes--the new MKZ will face in the comments below.
