Is this an appropriate price for a 2021Specialized Diverge?

Saw on FB marketplace a specialized diverge for $1,200.

It comes with

1×11 drivetrain
40t RaceFace chainring
GRX RD-812 rear derailleur
Ultegra shifters and brakes
PG-1130 10-42 cassette (brand new)
Ultegra chain (brand new)
S-Works seat post
DT Swiss R470 wheels
Maxxis All Terrane 700×33 tires
Replaced earlier this year: bottom bracket, brake bleed, shifter cable

I try not to buy used, but the seller is like.. ten minutes from my home and it’s one of the only bikes in my size on FB marketplace so thinking about hoping on this.
