I would think that an 07 has at least the balance of the warranty, maybe the 7 year 70K, or even the lifetime power train. I bought an 04 and was given 7 year 80K because it was considered a certified pre-owned. I am certain you got some type of extended warranty included. Check with your dealer. You should not have to buy it, only if you want to make it a "wrap" or warranty that is like an extended bumper to bumper.
