I live in the DMV (Washington DC area) as well and did a lot of research. Turns out I only found one dealership in the area NOT doing the Adjusted Market Value crap. Most are forcing you to pay thousands just for the "privilege" of being the first kid on the block with the 2023 CR-V! This dealership does add in the dent and protection plans (which come out to ~$1,200) but I figure you are at least getting a tangible product/service. And be aware of dealerships also doing the non refundable deposit, DONT DO IT. It's a sneaky tactic to lock you in as if you walk, you lose it! The car is very popular in this area and will sell itself so its not like if you change your mind, it will just sit there indefinitely.
So the dealership is called AutoNation of Dulles (Sterling, VA). My wife and I were extremely pleased with their customer service as well (as that too strongly factors into our decision). As for one's to AVOID at all cost: LandMark Honda in Alexandria! My wife and I had a very bad customer service experience (their management didn't give us the time of day and would not even bulge to negotiate!). Which is unusual because most Honda dealerships in this area have decent (at worse) to good customer service experiences. Our salesperson was actual nice and tried to be helpful but her hands were tied. We found out she ended up quitting a week later because of their toxic environment.
Bottom line, you want to look at the buying experience wholistically and get what you feel is most important out of it to get the best value. But don't settle on the first place you go and shop around, deals are to be had. We also discovered another dealership a bit further away (in Richmond, VA area) called Colonial and they too do not do the markup. If you are going to save thousands and get value, it might be worth the trip. Also, don't let anyone fool you by stating we are throwing in free maintenance for two years - Honda USA corp. is offering this for every new 2023 CR-V!
