I sent an email to my SA yesterday with the hope that since I got the text saying my car was in transit last Friday, maybe it had shown up early and I could come get it. He called me at the end of the day and let me know the car hadn't arrived, and is still scheduled to arrive Saturday, maybe Friday. He said we may end up needing to push delivery back to Sunday even, but he's keeping my appointment for later in the day Saturday in hopes it arrives in time that they can go through it and have it ready. So it pretty much seals it that I won't get it any sooner than this weekend. Honestly, at least know that's the case and not wondering whether it showed up early and it's just sitting on the lot until my appointment does make me feel better. Plus, it's just a few more days, and my work schedule is busy enough that they'll go by quickly.
Here's hoping yours shows up on time and you can still get it tomorrow!
