I Have an 08 plate Smax and there is water leaking into the boot area. Its coming in somewhere above the wheel arches in the rear of the car, and above the windows. If you remove the internal inspection panel for the lights and reach up you can feel the metel work is wet and the carpets are soden so that it has collected about 3 inches of water into the rear storage compartment as where the spare wheel would be. I am at the end of my wits re this as its the second car I have with this problem. I have taken the light clusters out and they are dry. Autoglass say it cannot be the windows as the seals are good. HELP ME PLEASE ! ! ! ! ! ! ! ! ! !!
