What is this bike worth?

[Benjamin]

Thinking of selling a 2019 Canyon Endurace CF SLX Disc 8.0 Di2, but don't know what a fair price is (bike shop tells me it's a sellers market!).

Condition is very good, relatively low miles, uncut fork.

Stock except for a Rapha Pro Team saddle, and has the Canyon Garmin mount added.

Nice shape save for some scuffs on the crank arms and some scratches on the crank arm tips.

Not really interested in shipping it, so that may affect price.

thanks!
