I wish you well but there is a thread dedicated for selling used Tesla’s. I also have a 2016 model X. AP v1. Already have 2 model3s and thought of replacing with a third one but will wait to see modelY. Mine has 8000 miles on it in great condition, no battery loss but with improvements I doubt I would get 60K. So depending on reason why your selling (if rapid sale wanted) may need to adjust that price
