Both our Bonneville'*, the 1992, and the 1995 have holes in the rear wheel wells. I'm assuming this is a very common problem on the Bonneville'* because I've been shopping for one and most that I look at have the holes through the rear wheel wells causing the water to end up either in the back seat of the car, or in the trunk! On most that I have seen, the passenger side seems to be much worse than the driver'* side. It starts off with the rubber sealer falling off, then it just rusts through. Just thought I'd give you guys a heads up so that you could check out your cars and see if this might happen to you before you have a leaking trunk like I do.
