A friend's dad -- InsideEVs Podcast regular, Kyle -- just went through a similar ordeal. Was assured there was no markup, so drove 3 hours to try out a rear-drive version and then was a told, by a different dealership employee, it was thousands above MSRP.
He was unhappy and made a video telling the story which got a lot of views. The dealer got back in touch and offered him the original deal, but he turned them down on principle. But then, besides harassing calls, messages, the dealer got a death threat so they removed the video from YouTube.
Anyway, maybe we should make a new thread listing dealers selling at or below MSRP.
Wish I could add my local dealer, but they have a $5,600 upcharge they call "Werner Care," instead of the more blatant "market adjustment." They include a number of extras you probably don't need/want worth, they say, $8,000 to make it at least seem like you're getting something for the extra money.
I plan to go over and take a test drive and see if you can buy without the "Werner Care" package, but I strongly suspect not. It's added to every model on their site.
