Devinci Leo 105 Road Bike

Wondering how much to offer for this bike/what's a decent deal?

Purchased new in 2024.

Like new condition with less than 1000km on it. Not a scratch.

Upgrades:

Vision Trimax 35 wheelset

Shimano SPD 105 pedals

Fizik Tempo Argo R5 saddle

Giant Contact SLR carbon hnadlebar

11-28 Ultegra Cassete CS-R8000

Continental GP5000 tires (less than 500km)

Thanks
