Well it was bound to happen sooner or later :(
After being the second owner of the car since September 2003, at 99,935 miles the original 1990 back window cracked while putting it down Monday night after school. I've wanted to cut the window out and replace with tinted vinyl since I got the car (this is my first/only car that I've ever had that has not tint), and this might finally be the reason I need. But knowing how much work is involved, and knowing the rain rail is 22 years old too, I might just bite the bullet and get a new cheap top. I don't drive it in the rain, and don't really ever put the top up, so an eBay special has my name all over it.

And the yellow on the window is dust - my back window is actually still damn near crystal clear after all that time.
