Mine isn’t that bad - only 20 years old but has seen all sorts of things from rocks and sand to hail and is just pitted bad enough to be annoying. But it’s that fact that I’ve seen the abuse it’s gone through without the first hairline crack that makes me cautious to get rid of something that’s stood the test of time. It’s either the angle or the glass (doubtful), but at this point it can’t be just luck, right? I just hear horror stories of replacement glass that isn’t fitted right, leaks, or breaks early on. I can deal with it a bit longer.
