Good Deal – first Bike?

Specialized Roubaix Pro SL3, Carbon, Shimano Ultegra 3×10
New to the Sport.
Looking to join my friend group that's into biking (for some of their more casual tours)

Seller is asking for 400€
Seller said service was done last time 2 years ago and basically not moved it since.

Does it sound like a good deal to you?
Thanks for the help – I'm a bit lost😅
