Water in the boot

[Monkey]

Hi, my car's on a 06 plate.  There's a puddle underneath the spare wheel, yet the boot shelf is dry.  I don't understand where the water's coming in.

Comes in under the black plastic roof seals, usually the driver's side, very easy diy fix, there are lots of posts on this forum, very common problem on older jazzes, the original sealant cracks with age, just needs new sealant, don't use ordinary silicone sealant as it doesn't last the harsh weather.
