09 Vibe after market sunroof

[rrtwis]

I just got my Vibe two weeks ago and love it. I bought it off the lot and it's the 1.8L engine so it didn't have the sunroof. I want to put one in but one Sunroof installer said that he would have to locate the sunroof way back behine the drivers head because of the slope of the roof line. Has anyone had a sunroof installed on a 2009 and have any tips for me?

Where is the stock sunroof installed? Can't see why an aftermarket one would be any different.
