It looks like you can't buy from Hyannis in California, however Saccucci is ok. I read at some of the above comments and I sure hope it covers the android/apply car play and such.
About $23,500 OTD is what I've seen others have gotten. Try using Costco, you can probably get it for that price with them. $24,600 seems kind of high try to get at what others have gotten it for about $23,500 OTD or even less.
Maybe some has said this already but definitely get your free annual credit report from the 3 bureau's from annual credit report. From what your describing, it sounds like a sleezy sales man trying to con you. Check with your credit union/bank if you haven't already.
