Sell Upgrade Parts?

I just got my Forza 6 Bundle an started racing and now i’m a little bit confused , is there no way to sell bought upgrade parts or do i just missed something?

I don’t think there is a way to sell part upgrades anymore. I looked because I was trying to use it to create naturally aspirated versions of some stock boosted cars using the upgrade to turbos and sell the turbos loop hole that had existed in other games. I’m assuming the feature was removed as the easiest way to close that loop hole. It is too bad. There are some cars that are really fun with less power and it appears any method for removing power either than way or with engine swaps to lower power engines have been removed.

You cant sell parts, I miss forza 4!!! but I that forza 6 might be better, I need lil more playing time to tell!!
