I just got one (2018, LWB, XL wagon) a couple of months ago and am happy with it. I found a lot of them for sale used at government GSA auctions, some very lightly used and in good condition. You do have to register as a GSA buyer and get verified but that's free and not hard to do. One bonus I found is that in my state (WI), the vehicle was tax exempt because I bought it from the government.
Here are current upcoming TC auctions: https://marketplace.gsafleet.gov/sales/browse-vehicles?saleEventStatus=Coming+soon%2CActive&make=FORD|TRANSCON&status=0%2C1%2C2%2C3%2C4%2C5%2C6%2C7%2C8
