N, no, no!!! The water in the caller's miata is NOT coming from the convertible top leaking! There are drain plugs in each side of the car in the tracks under the door. These drain plugs accommodate the run-off of the convertible top as it comes down the side and back of the car and runs down the back. When those drain plugs get clogged with road mud or pine needles or anything else that tends to plug up the drain, then water begins to flow into the floor. It tends to collect in the back and when you step on the brake, it flows to the front. This very thing happened to me with my LeBaron and I finally got the answer from someone on the lebaron listserv. Once we went under the car, located the drain plugs and cleaned them out, we had no more problems with water. We did have to take out the carpets and dry them, but this solved the problem with NO COST! Have him look under his car on each side for those drain plugs!
