98 GS Trunk Leak

[CapeGN]

Hello,
I own a 98 GS and discovered that I have water leaking into my trunk and settling in the spare tire well. I locked myself in the trunk while my wife sprayed water, but I wasn't able to pinpoint where the leak was coming from. It does look like it has been leaking for sometime now.
Is this a common problem?
If so, has anyone been able to pinpoint and repair the leak?

Thank's

When my GTP sat outside for a long ass time without being driven I had the same problem. I have been unable to duplicate it. I think it's where the spoiler attaches to the trunk. I know some people have had some pretty rusted out trunks because of this. I'm afraid to see what mine looks like.

I own a 2000 Bonneville SSEi that does the same thing for some reason!!
