Constructor Function

Can someone please help me with this Challenge:

"Modify the 'Car' constructor function so that it takes an argument for its model and set its 'model' to the model passed in from the argument."

<script>


      var carPrototype = {
        model: "generic",
        currentGear: 0,
        increaseGear: function() {
          this.currentGear ++;
        },
        decreaseGear: function() {
          this.currentGear--;
        } 
      }

      function Car() {

      }


    </script>

perhaps 

  function Car(model) {
    this.prototype = carPrototype;
    this.model = model || carPrototype.model;
  }

//tests
console.log((new Car("Mazda")).model);
console.log((new Car("Sedan")).model);
console.log((new Car()).model);
