I commend you for walking out. This is the buyer's best tool. A word concerning 'Extended Warranties'. They are actualy Service Contracts, not a warranty. If you choose to get one, know that the price is negotiable, even if they say it isn't. If they say it is not, then walk. If you still wish to get this optional coverage, BUY ONLY THE ONE OFFERRED FROM THE FACTORY! i.e. HondaCare for Hondas etc. The dealers offerred others as they make a higher profit on them. These are harder to administrate in the dealers' service department as many of them require prior authorization and if the dealer is in California and the Warranty Co. is in Pistol Grip Arkansas or further back East, they must wait until the next day. This is not good for the service department or the customer. I know. I was a service manager for over 30 years. The factory backed HondaCare covers what it says it covers. Period. No prior necesary. Everyone is happy.Back when I got my 2012 CR-V the dealer finance guy told me it was the law that I had to watch this video on an aftermarket warranty they were trying to sell me (not the Honda one!) and I had to sign a form that they had in fact shown it to me and that I had declined. I called them out for BS and told them no way in hell would I watch it or pay for it. There is no such law!
Dealers will tell you all sorts of bull chit to try to milk more money out of you. I have been known to walk out and refuse to finish a deal when they play these games. (they back track really fast when you do that). As for getting your money back, you can try but I am betting they will fight it and not admit saying any such thing. They will swear they were honest with you and you misunderstood or just changed your mind. They lied to you once, why would they be honest now?
