Price check — what's my full Simagic + Sim-Lab rig worth used? (EU/Netherlands)

Looking to sell my complete sim setup soon and want a reality check on pricing before I list it. I'm in the Netherlands, so EU pricing / euros ideally. Everything works perfectly and is in like-new condition (been travelling a lot so it's barely been used), bought around June 2025. No original boxes, unfortunately.

The setup:

• Simagic Alpha EVO Pro (18Nm) wheelbase
• Simagic GT Neo wheel
• Sim-Lab GT1 Pro cockpit + Vario monitor mount
• Sim-Lab Speed 1 seat + slider/bracket
• Sim-Lab XP1 loadcell pedals (2-pedal set)
• Samsung Odyssey G5 34" ultrawide (3440×1440, 165Hz, curved)

A couple of questions:

1. What's a realistic bundle price to sell the whole thing as one lot?
2. Am I better off parting it out? If so, which pieces hold their value best vs. which are a pain to move?

Appreciate any input trying to price it fairly so it actually sells, not just sit there. Thanks!
