Wife just bought a 98 xj8L (nice ride-her 3rd British car-must be trying them all) and the windshield reservoir is sticking down so low that it got hit by a parking strip or something and make a hole in it. Couldn't believe they located it there, but anyway, it there an aftermarket supplier of these, or do I have to get a Jaguar part? Also, what is the dif with the VandenPlas's?
