//CUSTOMER METHODS (BEHAVIOURS)------------------------------------------------------------------------------------------

//Rather than defining methods in the constructor function above, I attached methods to customer prototype, such that
//any customer can access the methods 


//[Method1- Give customer a buyCar method which removes Car from dealership and updates their car property]:

Customer.prototype.buyCar =  function (car) {

            console.log("Thank you for your pruchase " + this.name)
        
        //reducing amount in wallet because just bought car: same thing as: this.wallet = (this.wallet - car.price)     
        this.wallet -= car.price 
                console.log("your wallet amount is now £" + this. wallet)
