I got in my Mk1 this morning, and noticed that my rear carpet was very very wet. Wet to the point that there was a visible puddle. Not good! I'm really not sure where all this water could be coming from, I was driving through rain last night but the only little leak I notice is from the very top of the windscreen where the seal joins, but that's just the occasional drip. Where on earth could all this water have come from? I know I haven't spilled anything in the back, and didn't leave any windows open in the rain.

I just find this odd because the footwell in front of the crossmember is bone dry, no leakage of water whatsoever.

Also the car is parked in an undercover garage, so it definitely would've come in while I was driving.

Any help would be greatly appreciated!

seal up where it's occasionally dripping and see if it forms again you'd be surprised how much water can get in just from a small drip.

Best thing that people say to do is sit in the car and get someone with a hose to spray around the area and see where its coming in

The drip at the front just goes straight onto my hand / the gear lever / the front carpet though, and it's very minimal, as the front stays completely dry. I've just finished drying out the back and I managed to fill up a bucket with a couple of inches of water, which seems like a huge amount in comparison - it's as if water has been gushing in somewhere while I've been driving along.

I'll have to give this a go tomorrow! Sounds like a good idea.

as you park under cover, and its the back id be looking at the heelboard / wheel arch area. lots of water get thrown at this area by the wheels.

+1 on the arches and heelboard. But as mentioned the best thing to do is whip the carpet out, dry everything off then get a mate to hose the car down with you sitting in it, paying particular attention to the door seals and rear of the car.

Bear in mind though the flutes in the floor will allow water to travel from front to back and vice versa.

I've taken the Mini for another drive in the wet today, this time without the rear carpet in place - I think I've identified where the water's leaking in, it appears to be coming from the bottom of the crossmember which holds the seat brackets. What I don't know is how it's finding its way there and into my floor. Should I maybe drill a couple of drainage holes along the bottom of the crossmember and along the sills?

You need to find the root cause of the water ingress before you drill anymore holes.

I'll have to try getting the car up on a ramp to see if I can identify where the water is coming in, because inspecting it while on the ground hasn't really revealed anything - I can't see any obvious holes and the car is quite rust-free.

Its possible then its either a door seal or the drain holes in the door are blocked causing water to pool in the bottom of the door and leak through the door card membrane if there is one.
