Need advice: New Trek Domane AL 2 Gen 4 vs. used Domane AL 3 Gen 3 — which is the better deal?

Hey everyone! I’m looking to get my first proper road bike for general fitness rides (1–2 hours), commuting, and maybe training for a triathlon later on. I don’t need anything high-end, but I do care about getting the best value for the money.

Right now I’m between two options:

1. New Trek Domane AL 2 Gen 4 — 7,500 DKK (on sale)
   • Brand new
   • Shimano Claris 2×8
   • Disc brakes
   • More modern frame design
   • Comes with warranty

2. Used Trek Domane AL 3 Gen 3 — 6,600 DKK
   • Good condition (see attached pictures)
   • Shimano Sora 2×9
   • disc brakes
   • About 1.5 months listed for sale
   • No warranty, obviously

⸻

I’m mainly wondering:
• Is the used AL 3 priced fairly, or should I offer less?
• Is the AL 2 Gen 4 actually the smarter buy because it’s new and only slightly more expensive?
• For someone who wants good value and doesn’t need anything fancy, which one makes more sense?

Any help or opinions would be greatly appreciated!
