This may be posted at the wrong spot, but I'm wondering if anyone can break down (no pun intended) what often-replaced items fall into which catagory of the warranty. In other words, what is covered in the 36K mile portion, and what is covered further into the 60K mile portion. Did most of you guys purchase Nissan's extended warranty? I didn't buy it because I've always heard extended warranty's are a total waste of money, but now I'm thinking it may be valuable as I drive about 35K per year, which is going to burn up the factory warranty pretty quickly. I appreciate any input you may have about the warranty period!!
