I would suggest "Starmark", the warranties offered by others are good to horrible. I have had good luck with factory supported warranties, and have had bad luck with independent warranties sold by the dealer. The case in point is that I purchased a "GM Extended" on a used car and got my moneys worth. The next "caddy" dealer sold me an "Extended" non GM policy on a brand new car and told me it was as good if not cheaper, the company was out of business when my warranty ran out. There was no help from the dealer on that one, they took their commission up front. I have heard of stories where the dealer has to call for approoval and sometimes the tell them to "band aid it" or want to negotiate it!
Like a rear end making noise, will not be repaired untill it fails!
