I have had my stinger since January 18th 2018. And that being said I stopped driving my 240sx until recently (only drove it 2 times haha) I've got about 10,3xx miles and it's a dream. Raced many things, lost only once. Needless to say my goal is to hit 100k miles before my 10 years are up.
Have you tried a tiny amount of silicone grease on the weatherstripping? I forget where, but I read about how that can fix one version of the creaking...
