2007 MAZDA MAZDASPEED3 Structure Problems

MY VEHICLE LOST ITS ENGINE OFF THE MOTOR MOUNTS! THE CAR IS A 2007 MAZDA MAZDA SPEED 3 WITH 6260 MILES ON IT. DURING DOWN SHIFTING FOR A TURN I HEEL-TOED, PREPARING FOR THE NEXT GEAR AND A RIGHT TURN, COASTING AT ABOUT 30 MPH. DURING THIS ROUTINE ACTION THERE WAS A HUGE CRASHING, METALLIC SOUND THAT CAME OUT FROM UNDER THE ENGINE AREA. THEN I FELT A MASSIVE PULL ON THE CAR, AND A HEAVY GRINDING, POPPING, AND CLANKING SOUND. I COULD BEST DESCRIBE IT AS IF A GORILLA HAD JUMPED INSIDE OF THE HOOD, AND STARTED ATTACKING THE CAR, FROM WITHIN. I MANAGED TO COAST THE CAR TO A STOP, AVOIDING PERSONAL INJURY, BUT IT WAS CLOSE. IF I HAD BEEN GOING AT HIGHWAY SPEEDS, I HAVE NO DOUBT I WOULD HAVE BEEN SERIOUSLY IN PERIL. I COUNT MYSELF LUCKY. AT ANY RATE, I QUICKLY PULLED THE CAR...
