Sorry, just kidding.  Modern engines rarely need any break-in anymore.  In order to extend the lifespan of the cares, it's always a good idea to be gentle in the first 500-1000 miles.  Be gentle when accelerating the car and don't race the engine.  The most important thing is not the miles you have driven but how you drive it.  Don't drive car in a constant speed but vary the speed instead.  Old school advice is not to exceed the speed of 55 mph but it's not very critical anymore.  The critical thing is to vary the speed to let the new piston sit well.  Good motoring!
