Yes, that’s fair.
Why are you selling?
An X4 is a recent model.
I would hang on to it if it were me.
If ever you do mods or want to go to a tuning house, you’ll need one.
It works with all Ford models.
Things as simple as different tire sizes or a gear swap.
You can tell the car what you did so your speedometer stays true, and your transmission keeps shifting properly, if it’s automatic.
And last, you may not have used it but if you do get rid of it, make sure it is not married to your car by previous owner before you do.
Make sure your car is running on its stock tune.
If it is still married to your car a buyer won’t be able to use it, and your stock tune will be stored in it.
You need that stock tune if the dealership ever has to do any updates to your ECU.
You return to stock, dealer does update, then you dump after market tune back in.
