you should check the rear window seal, the tallights seals, and the spoiler bolt holes

You could remove some of the interior trim inside of the trunk like the two sides and rear body panel. Then, with a flashlight, hop inside the trunk and close it while someone gently sprays water on the trunk. Look around where the tail light mounts and seal where the trunk lid meets the gasket/weatherstrip.

Dont forget to leave the keys with your helper

I found that in mine the watter seems like it is leaking from where around the metal joints which are at the bottom of the back window. The location is right above the wheel hump.

It is right around where the ground for the antenna is. A little up and left in the picture from the antenna ground. (BTW my ground location has since been moved)

Here'* a weird one that might help. Still can't believe it was the solution. I was always getting water under the jack box. Any time it rained, driving or parked, I would get a small (sometimes large) puddle. I removed the jack box and the trim covers on the passenger side. Went out during a rain storm and felt around, all was dry up at the top but the puddle was growing under the jack box..
It turns out that there is a bracket that holds the bottom of the jack box. It is bolted down to two screws that come into the body from under the cladding. Somehow the water was coming in, running down the underside of the jack bracket and dripping down onto the trunk floor.
I covered the stud and braket to sheet metal seam with blue silicone and now no leak...
Might be worth checking on your car.
To this day I have no idea why the water seems to come "up" and in, must puddle on the top of the cladding somewhere...

I'd put money on it that your inner quarter panel has a rust hole in it. I had an Olds 88 that had the same problem. Climb under the wheel wheels in the back and look for a hole.

When I had water in the trunk, it was a taillight stud had broken, which made a gap between the taillight seal and the body. I just put silicone on the seal, and all is dry ever since.
