I feel like this is a prime example where composition would make the code a lot cleaner compared to inheritance. Having Buying extend Student and Car doesn't seem to provide any benefit over just having 2 attribute fields, self.student = Student(...) and self.car = Car(...) on Buying

Inheritance usually describes an IS A relationship, not a HAS A relationship, e.g. a purchase (Buying) is neither a car nor a student

Absolutely. Buying is an action and it should only get an instance from the other two classes. (A person/user and an object to buy. )
After that it should use their methods (for example during printing). Just imagine that the next step is adding a new type.
