     var doors: Int

    // Designated initializer
    init(wheels:Int, doors:Int){
        self.wheels = wheels
        self.doors = doors
    }
}

class Car: Vehicle {
    // A car must default to 4 wheels and 4 doors
    init(wheels:Int, doors:Int){

You have correctly initialized wheels and doors, but your super.init method is wrong. Try and see if you understand why the following is the correct answer: 

class Vehicle {
    let wheels: Int
    let doors: Int

    // Designated initializer
    init(wheels:Int, doors:Int){

    self.wheels = wheels
    self.doors = doors

    }
}

class Car: Vehicle {
    // A car must default to 4 wheels and 4 doors
    init(){
      // call super.init
      super.init(wheels: 4, doors: 4)
    }
}
