Can the landlord tow my vehicle if it sat on flat for three days while I was out of town?
What does your lease say? What laws does your state have about abandoned vehicles? How long was the car inoperable? These questions are key to the answer to your inquiry.
A contract which a Court believes gives too much of an advantage over a consumer can be held to be void as unconscionable. If the terms of an agreement in such a circumstance were deemed to be grossly unfair, the contract could be held to be void as unconscionable and therefore contrary to public policy. Unconscionability means that the actions of a party to a contract are so outrageous and oppressive as to shock the conscience of the Court and invalidate a clause or provision of the contract or the whole contract itself.
