in churning, we have a phrase called HUCA, hang up call again. frequently, the right hand does not talk to the left hand, so you keep trying different paths (nicely within reason) and hope that you want gets through for one reason or another.
i'm in a similar boat, so really interested in seeing how this works out. maybe try your DA instead of sales to see what they say or can do, or try going through with the purchase all the way to financing and maybe they'll soften their stance, or maybe call lucid financing or BOA and see what they say when it's time for your to finalize everything.
