Sounds like a great deal.  Got mine used for the same price of $2200 back in March 2020, with 100 miles on the ODS, mine came with metal panniers that I didn't use, and chose to buy regular panniers. Mine is still going strong without any issues.  Last year did upgrade to a Redshift stem and seat post for comfort.  I also have a Specialized Creo so that gets most of my usage, and the Quick-E still has relatively low mileage. That brand new 2022 Trek Allant 7s stagger does sound like a good deal though, since it includes a warranty.
