I just got a call from the dealer. I ordered on April 13th. Apparently they weren't expecting my order to be pulled until July, but they just got an update that a June production spot became available and my order should be pulled next week. Who knows what the details are. Perhaps somebody else in front of me at this dealership cancelled, or maybe a large shift in the production schedule happened at the plant. Fantastic news, any way. This will probably result in an early July delivery, which will put me at the 3-month order-to-delivery time frame that seems to be the average.
So if you're staring at a huge wait time like I was, don't give up all hope.
