I’m down to two SUVs and can’t decide

I’m shopping for a luxury SUV and I’m between a 2023-2024 Audi SQ8 Prestige and a 2023-2024 BMW X5 xDrive40i/M60i.

Here’s what’s throwing me off… I keep hearing people say they’re getting $10k-$20k+ off MSRP on leftover new models, plus 0.9%-2.9% financing, which makes me wonder if buying new actually makes more sense than buying a 1-2 year-old used vehicle.

For those who have recently bought:
-Did you buy new or CPO?
-How much off MSRP did you negotiate?
-What interest rate did you get?
-Is there a sweet spot where buying new actually beats buying used after incentives?

I’m trying to make the smartest financial decision, and get a bad ass ride I plan on keeping for the next 5+ years. Appreciate any real-world experiences.
