When it rains a lot, I get water on the passenger side floor (front and rear) in my '91 Shadow convertible. Is there a drain plugged up somewhere? I also hear water sloshing around in the rear when I hit the brakes while backing out of my drive.

 

What condition is the top? Garage it or get rid of it. Rag tops are known for leaking water into the car even with new tops.....

 

Even when new we had trouble with leaks. The dealership would always bring in an expert to adjust the top to fit. Sometimes it would take him 2 days. If you want to try yourself use a lawn sprinkler not a hose. If you can find the source of the leak you might be able to fix it yourself. If not you can at least point an expert in the right direction.
