I am looking at a '97 SC2 that has a heavily stained headliner. The sunroof is currently in a non-working condition. It seems to be the entire headliner too, like it has done this for a while. I have seen references to sunroof water leaks, and wonder if this consistent with what others have seen regarding leaky sunroofs. I wouldn't be opposed to sealing off the entire unit, if I knew that the sunroof was only leaking through the area around the glass. I would appreciate hearing from anyone that has experience with this problem.
