I WAS DRIVING ON GLADES ROAD, BOCA RATON, FL. I HEARD A LOUD NOISE, SAW SMOKE AND LOST MY POWER STEERING. I MANAGED TO PULL INTO TOWN CENTER MALL, GOT OUT OF THE CAR AND SAW THAT THE CAR WAS ON FIRE. THE BOCA RATON POLICE CAME, #5 FIRE DEPARTMENT CAME. THE FIRE WAS PUT OUT AND THE CAR WAS TOWED TO MERCEDES OF DELRAY.
