Leaking jaguar XK8

[Jeremy Lloyd]

I have a 1998 Jaguar XK8 which has seen life. It will soon be having its first MOT in my stewardship so fingers crossed. The car leaks rainwater into the rear seat wells via the two rear side windows. I have removed the rear seat squab and backrest and am reluctant to remove the interior trim as I am afraid of damaging it. Any suggestions would be appreciated.
