Used Endurace CFR AXS or New Endurace CF SLX 8 AXS AR60

To be honest, I don’t know what to do. I want to buy a Canyon Endurace, specifically one of the two mentioned in the title. Which one should I get? What would you choose and why?

The Canyon CFR is used, and I don’t know what condition it’s in, but it’s 700 grams lighter. The SLX is heavier but comes with the new Reynolds AR60 wheels, which I believe are faster, and the bike looks better. The CFR has the older RED D1 groupset, while the SLX has the new SRAM Force D2 groupset.

I’d appreciate some arguments on what you would do in my position.
