Dealers are expecting to sit with cars longer now, given the rise in interest rates and don't want to overpay for them or they'll make a loss, hence the low offers on these websites. Additionally to this you have customers cancelling orders and dealerships being on the hook for these cars as well (look how many mk8 R's are for sale!)
As Hertsman has said, cost of change is what you're looking at. I've been tempted by a local TCR, but the cost to change in beyond my budget, even including the beyond budget max.
At the end of the day manual or automatic it's the same car, what you like about the car you'll still like and what you hate you'll hate.
