I'd be surprised if your's isn't pitted all to hell. You should see mine (also a 93TT). I still have the original windshield, and its horrible. (although to be fair I put a lot of highway miles on the car while I lived up in Fort McMurray... and that was certainly where I got the bulk of the pitting/chips from).
