I'd imagine you have a vinyl roof - the cloth type are aftermarket on that series.

Check the soft top drains to make sure they are not clogged. The drain tubes exit just in front of the rear wheels.

It is possible that the rain rail is cracked but more likely to be clogged drains. Check the drains and report back.

check behind the seatbelt towers.. i.e. sit on ur chair facing the rear of your car.. place your hands on the outer edge of the parcel shelf, and trace it towards yourself whilst sticking to the edge of the parcel shelf.

at the end of the parcel shelf, there should be a little compartment of plastic. check the drain holes in there. u may need a flashlight. clear out all the gunk that's in there. i had the same problem when i first got the car. to check if it's been cleared, just pour some water and step outside your car. have a look just infront of the rearwheel, water should be draining out from there.

The best way to check where its leaking is this (assuming its not the drains):

With the top up and latched
1. remove the carpet and padding from the parcel shelf
2. Get 2nd person with a bottle of water.
3. You sit inside with a torch and park your car in a well lit area
4. Get assistant to slowly pour water around the edge of the softtop
5. you spot the water leak

Assuming water does come in via the rain rail, note if its coming through just below the nuts that hold the top in place or between the nuts. If its through the nuts, its an easy fix. If not you may need a new rain rail. Not a difficult job but fiddly.

Currently am just using car wash

I believe the '03 classic had a fabric/cloth roof standard.
