Nobody is going to pay extra for tint and paint protection, fyi. Check the KBB value for private party, excellent condition. If it's more than you owe, then you're in good shape. If it's less than you owe, you're not going to be able to sell it and pay off the loan. I would never want to be paying off a loan for a car I no longer had.
