How old does one have to be to buy a car in KY?
To buy a car anywhere in the United States, the buyer must be
legally able to enter into a contract. To be legally eligible, the
person must be over the age of 18, or must have been ruled by a
court as an emancipated minor. As long as the buyer meets either of
these requirements, he or she is legally allowed to enter into a
contract and thus allowed to buy a car.
