By dropped the deal, do you mean dropped the price or you’re still shopping? If you’re still shopping, here are few recent deals from Washington state that you might be able replicate (try reaching out to people on the thread and see if they might be able to share the dealer/salesperson or maybe the 2nd best deal they were offered etc):
Signed -- 2025 BMW i4 xrive 40 36/7.5k -- $389 inc tax + 3000 DAS + 3150 MSD - #7 by Usr377 (this one had 3k due at signing)
There are also still quite a few Mercedes EQBs available in the same price range as your Equinox deal, check the Marketplace and consider grabbing an AWD EQB?
