Well 3 out of the 4 things that happened to you are from aftermarket parts. So I think your actual subie has held up pretty good from being a daily driver and autocrosser. If your clutch and CV have been the only problems in the time you have owned it, thats not to bad at all. And it is tight that whiteline and vishnu will replace their faulty parts. Excellent job for both companies.
If you do sell your car, you know I will grab some of those parts off yea
