Just find the best deal you can and pull the trigger on a '19 or '20. There are no guarantees on anything newer. Since I know you're a realtor, you should consider it like "land", they aren't making any more of it, as far as we know.
If you sit around waiting on the best absolute deal possible, you will likely have to settle for something that's not exactly what you want. Not saying it's not possible, but after a few months of driving it, you'll forget about a grand or two, either way.
My way of thinking also. I'm keeping it a long time so whether it's $67, 70 or 72, I'm going to get exactly what I want.
