Some will for sure appreciate all the efforts that has gone into this. No worries there.
One good advice I can give you tho.... from one serious modder to another, you will need to let go the emotional link you have with your car before even thinking of letting it go (less frustrating when others throw rocks and leaving blood on the floor). Just think of it as a car (hence my comment above) and not your baby anymore. If you can pass that, which clearly you haven't, that should put you back on track in a flash
Luck with the sale and sorry for sounding like your dad or something
