..depends on if the sunroof is important to you or not.

I like the sun roof especially since the AC needs refurbishing. I'd rather fix it than plug it. I'm trying to get things fixed without rigging (poorly).
So, to summarize, seals should keep some water out of the roof but the drains are designed to handle the amount that "should/may" get in.
Roof itself can be adjusted to help seal.
Seal may be able to be refurbished IF it responds positively to PS fluid with stop leak. Others have opted to squirt silicone and be done but that doesn't always work.
Frame may be rusted which would leak and not be fixed by any of the other suggestions.
More info to determine exact circumstances on this particular car needed.
