Sourcing a new-ish Audi w/ 100K in my pocket

[Toonces]

I'm looking to source a '22 or '23 Audi SQ8 or RS Q8 with 10-20k miles on it, highest trim package available. After doing a quick search on autotrader.com I'm not really seeing too many of them out there. I'm on the US east coast so finding one somewhere between New York and Miami would be preferable, but if I have to go as far as CA then that's alright too.

How should I go about searching for my next slightly used Q8?

Thanks!
