all upgrades applied are never undone. doesn't matter which event you decide to upgrade the car for, it will always stay AS YOU left it. my homage was at 2522 pro 2020 when I started this revival

along with cars used during events for example the cars required for enduro events stay the rank u upgrade to even if u don't own it.
