Any tips for finding a certified pre-owned Audi Q7 for sale?

Ive been an Audi driver for about ten years now, mostly sticking to the A4 or Q5 models, so I am pretty familiar with how the CPO process is supposed to go. I know all about the 300-point inspection and the limited warranty extension that comes with the Audi Certified badge. But honestly, trying to find a decent 2021 or 2022 Q7 with the 55 TFSI engine right now is becoming a total headache. I am specifically looking for the V6 because the 45 just feels too sluggish for a three-row SUV, but every time a good one pops up near Seattle, it is either gone in two hours or the CPO status is actually just a generic dealer warranty because it is at a non-Audi lot.

I have about $48k saved up and I really need to get this done before our road trip in July. I have been checking the national inventory tool on the Audi USA site daily but it feels like the data is lagging behind what is actually on the lots. Plus I am seeing some weird pricing where a 30k mile CPO is listed for basically the same price as a new one with incentives. Is there a better way to track these or maybe a specific time of month when dealers are more likely to drop the certified tag on trade-ins? Im starting to wonder if I should just look at a different trim or if there is a trick to getting first dibs on the lease returns before they even hit the website. How are you guys actually landing these without spending all day refreshing browser tabs?
