I'm assuming you don't have a VON yet? Usually dealers get a VON when they have a vehicle allocation and can actually place the order from Subaru. This holds your place in line at Subaru (but delivery still depends on Subaru's parts suppliers, etc). I got a VON for my car the same week I ordered, so I was first in line at the dealer. If Lafontaine can't give you a VON, then I would consider giving a few other dealers in your area a call to see if they have a WRX allocation open and can give you a VON the same day you order. Your order would start over, but at least then you would get your vehicle November-ish (maybe? I haven't followed the order thread recently). If Lafontaine does have a VON for you, then you will most likely be delayed more if you switch to another dealer.
Cars.com can show you if there is a WRX in a configuration you want at a nearby dealer too, if you haven't already checked them.
