Car is a subclass of Vehicle, and you didn't define an init method in the Car class. Because of this, Car uses the same init method that Vehicle uses. This means that you would instantiate a Car the same way you would instantiate a Vehicle:

let someCar = Car(withDoors: /*INSERT NUMBER OF DOORS HERE*/, andWheels: /*INSERT NUMBER OF WHEELS HERE*/)

I hope this helps!
