X Plan pricing on a prior model year is awful price.
I'll renew my call that you go in on the last sales day of the month. That is the best chance for a deal. I'd support making sure they have your phone number, make them an offer of no more than 55k, and when it's rejected, walk out, no games no discussion, walk out. Do it early in the day, and actually take up some of their time with a drive, talking about the options, look it over.
