Rainwater leaks - 205 - Andrew-T
The 205 has a bit of a reputation for water leaks into the boot, from where it will run into the well under the rear seats. A few months ago I took over a 93K car which clearly had suffered from this problem. Previous 205s I have owned have had leaks via the inside of the tailgate, which is cleverly provided with a hole in each corner draining into the boot! However that was not the problem with the new car, which collected water only on the nearside.

I removed the boot-floor coverings and started experimenting with the garden hose. Finally I found a tiny hole in the rubber sealant on a body seam at the lower corner of the boot opening - water was getting in from the space containing the tail-lamp cluster, and that looks the likely entry point. So I tightened down the cluster, sealed the small hole, and pushed a hacksaw blade up the seam from below to provide an exit for any water that may still get in. Time will tell ..
