Trek Domane SL5 – Unknown Year

I found this on FB for $1900. There have been upgrades: Electronic shifting, SRAM Rival groupset, Bontrager aluminum wheels, Bontrager Comp power saddle. The seller said it was a 2022 when I asked, but I'm not seeing 2022 come up for this color/image search. 2018 and 2019 have come up. I've asked for serial number and am waiting for them to respond with it. Is this worth $1900 with those upgrades? Thanks!
