    Question Traditional Singleton Implementation vs Static Object Singleton Implementation

    I have usually implemented Singletons as described in the Design Patterns book. Recently someone suggested another implementation of Singleton using creating a static instance of a class and returning that instead of using new and returning a pointer to the new singleton. I would like to get your input. Is there any advantages of using one or the other? Disadvantages? Disadvantages for the static singleton implementation?

    Let me illustrate:

    Traditional Singleton Implementation

    Car* Car::getInstance()
          Instance = new Car();
    	  InstanceFlag = true;
    	  return Instance; 
    	  return mp_Instance;
    Static Implementation

    Car& Car::getInstance()
       static Car theCar;
       return theCar;
    Advantages & Disadvantages? Any documents or articles I can refer to for the second implementation ? Thanks for your help!
