The soft tops are pretty good, the original ones leak around the seams and the hard plastic rear windows get brittle and crack. More often though you get leakage from blocking in the cabin air intake - theres just some open slots that fill up with stuff, dont drain properly, and drain into the cabin instead. I also have an issue where the windshield isn't a molded in piece, it's bolted on. kinda cool if you wanted to make it fold down but for me water collects above the doors and drains down the crack at the front of the door, then leaks into the cabin along the bottom of that windshield. it's not a big deal.
this has a lot of rust, including some holes though the floor, so it drains out anyway haha
