Since you are in California, you may be out of luck. I bought an extended warranty from Warrentygold in December 2001. They told me since then , California has passed a law that only dealers can sell extended warrenties, no third party vendors like warrantygold, or warrantybynet etc. You can check various web sites like, Autoweb, Edmunds, Yahooauto, etc. They may have links to extended warrenty vendors. However I don't have high hopes at this point.
You said your dealer won't sell you an extended waranty? That sounds strange.
