HELLO. I COLLECT HOT WHEEL CARS AND SO DO MANY OTHER EBAYERS. LIKE YOU IF I NEED A CAR TO COMPLETE A SET OR SEE SOMETHING I REALLY LIKE I TRY HARD TO WIN IT. LATELY I HAVE GOTTEN INTO THE ERROR CARS, AND THERE ARE ALOT OF FACTORY DEFECTS AND PACKAGEING. I HAVE STARTED A COLLECTION OF ERRORS THAT ARE BACKWARDS IN THE PACKAGES AND ALSO STARTED A COLLECTION OF CARS THAT ARE UPSIDE DOWN IN THE PACKAGE.I JUST WON A UPSIDE DOWN CAR AND WHEN IT ARRIVED IN THE MAIL THE CAR WAS RITESIDE UP IN THE PACKAGE. NOT WANTTING TO GIVE A BAD REVIEW I DID SOME TEST WITH THAT CAR A MUSCLE MANIA AND OTHER CARS WITH THE SAME SIZE PLASTIC ON THE CARD, AND TO MY SUPRIZE, BY TURNNING THE CAR UPSIDE DOWN AND SHAKKING IT AROUND SOME I WAS ABLE TO FLIP CARS UPSIDE DOWN AND THEN RITE SIDE UP AGAIN.I HAD ANOTHER COLLECTOR FRIEND TRY THIS WITH SEVERAL CARS AND HE ALSO WAS ABLE TO FLIP CARS IN THE PACKAGES ALSO!! THIS COULD MEAN THAT PEOPLE TRY THIS IN A STORE AND FIND CARS THAT ARE ABLE TO FLIP IN THE PACKAGE AND NEXT THING YOU KNOW YOU HAVE AN ERROR CAR UP SIDE DOWN IN THE PACKAGE!! IT DOES NOT DAMAGE THE CAR OR THE PACKAGE AT ALL AND YOU CANNOT TELL.. SO IF YOU SEE A CAR THAT IS UP SIDE DOWN, BEFOR YOU BID, GO TO THE STORE AND TRY IT YOUR SELF.( YOU MAY CREATE YOUR OWN ERROR CAR} GOOD LUCK AND WATCH OUT
