If a dealer tells me "yes, we honor the price but..." and the "but" part is not an obvious add-on like insurance or pre-paid service or anything like that that I can refuse and still get a car - I'd just walk. These people are obviously liars, why would you want to spend so much money with liars? It's not like there's only one place where you can buy a car nowdays. Same for extended warranties, etc. - if the guys can't understand "no" there are always guys who can. I've seen both kinds and the best way to deal with liar kind is to just walk. It stings when you've already invested time with them, but it's just sunk costs fallacy - the sooner you cut your losses the better.
