As I posted somewhere before - NO EXTENDED WARRANTIES for Subaru! It is my second one, and I have warranty on the first one - never used it, and that car pushes 80K miles now. BRZ/FR-S doesn't have turbo. And no turbo means - no problemo.
When its going to be closer to 3 yo, then I'll decide if I want to keep the car, get extended warranty from Subaru (!) or update it with the newer one. By that time I'll have much more data to make my decision. Right now - buying warranty is mostly out of emotional attachment.
