I find 25 EBII 335's on dealer lots nationwide according to cars.com. Most of them look to have the sport auto and be pretty decked out (premium/nav/driver assist/HK/cold weather). The dynamic handling appears less prevalent (although maybe not needed on 335i). BMW San Francisco has 3 335i's in EBII, so maybe they'll bargain with you?
If you are flexible with the AT and xdrive, I imagine you can find one relatively close (ie within 500 miles lol). If it was me, I'd really only be OK getting MORE options than I originally wanted (would hate myself if every day I asked "what if"), so it would boil down to being able to find/negotiate a price you can live with...
It seems like the real downer is the uncertainty rather than the wait, but rest assured it will eventually make it *exactly* to your spec
