Is this a good deal? 2015 Trek Emonda SL6

I’ve been using an old trek bike I got from a friend but I’m looking to upgrade to something that will last me a while. Just wanted to see if this is a good price and what to look for if I check it out.

The sellers post:

Upgrades include
-Dura Ace Front Derailleur
-Bontrager Duotrap Speed/cadence sensor
-Williams Cycling carbon seatpost
-Williams Cycling carbon stem
-Bontrager Affinity RXL Saddle
-Continental Ultra Sport 25mm tires

This bike has never been crashed or dropped, and is in great condition. Just got professionally serviced and rides great! Feel free to message me with questions
