WHAT COULD I POSSIBLY HAVE NOT TOLD YOU? I HAVE HAD THE CAR FOR LESS THAN 50 MILES. NOT TRYING TO BE AN A@# BUT I NEVER TRULY LET LOOSE ON IT. AS FOR GETTING THEM TO LOOK AT IT, I HAVE NO DOUBT THEY WILL FIX IT I WAS JUST WONDERING IF IT MIGHT NOT BE SERIOUS. BUT JUDGING FROM THE REPLYS I GUESS I WILL HAVE NO IDEA TILL MONDAY.
