They've never done it so it can't be done
We know better
...yeah money also.
Our local dealership will not touch used parts. They will always sell new parts because that's where they make their money. Every once in a while I will get a price quote from them just for a laugh. They make no effort to try to save you money.
The dealership is also only interested in current models. They're not going to train their employees on everything there is to know about the FF1, 360 or other extinct models.
