I have a 2000 SE without the sunroof option and would like to get one installed. Have any other SE owners thought about this too? Or have you gone through with it? I would like to know cost and how long it took. Also, I'm not sure if there is a difference in the roof of an SE without a sunroof compared to that with a sunroof. I have the the two map lights which have a bulge on the roof. Any help would be helpful.
