Time is on your side, then. With any deal, I am sure you are aware that the discount off MSRP, along with the MF and RV also play a part in the overall deal. I hope you are not just focusing on the current incentives.
For example, there are $20k in incentives this month on the Audi e-tron GT (I know it is not in the same class as the vehicles you are looking at). If you have Penfed, there is an additional $2k off. I just wanted to point that out.
