I PURCHASED THE NEW MIATA ON 4/23. WHEN GOING OVER THE FUNCTIONS WITH THE SALESMAN, HE PULLED THE EMERGENCY BRAKE UP VERY HARD. I WAS NOT ABLE TO RELEASED IT WITH BOTH HANDS. HE APOLOGIZED FOR PULLING IT UP TOO FAR & SAID THAT WAS NOT NECESSARY. I USED THE BRAKE A NUMBER OF TIMES AS I DROVE THE CAR WITH HIM AND THERE WAS A DISTINCT SPOT WHERE THE BRAKE WOULD STOP, WHICH I ASSUMED MEANT IT WAS ENGAGED. I ASKED THE SALESMAN FOR ANY FEEDBACK HE HAD ABOUT HOW I WAS DRIVING. HE WAS POSITIVE. THE NEXT DAY, WITH 77 TOTAL MILES ON THE ODOMETER, AND THE EMERGENCY BRAKE ENGAGED, THE CAR ROLLED FROM A RELATIVELY FLAT AREA WHERE IT WAS PARKED, DOWN AN EMBANKMENT, INTO THE WOODS AND THE FRONT END IS DESTROYED. THE TOW TRUCK DRIVER TOLD ME HE DIDN'T THINK THE BRAKE WAS FULLY ENGAGED, GOT INTO THE CAR & PULLED THE BRAKE INTO THE POSITION AGAIN THAT I WAS NOT ABLE TO UNLOCK EVEN WITH BOTH HANDS. I SHOWED HIM THE POSITION I HAD PUT IT IN. HE SAID HE UNDERSTOOD THE PROBLEM'THAT THE SEAT NEEDED TO BE FARTHER BACK TO GET A GOOD POSITION TO RELEASE THE EMERGENCY BRAKE, AND WITH THE FORWARD SEAT POSITION I USED TO REACH THE CLUTCH, THAT I WAS NOT ABLE TO PULL BACK HARD ENOUGH ON THE BRAKE. I'M 5'3". THIS IS A PROBLEM. I SHOULD ADD THAT THE CAR WAS NOT IN GEAR WHEN THIS HAPPENED. IT WAS IN NEUTRAL, WHICH I UNDERSTAND NOW IS NOT A GOOD IDEA. HOWEVER, I HAVE TO BELIEVE THE EMERGENCY BRAKE IS DESIGNED TO HOLD A CAR ON A FLAT SURFACE WITHOUT ROLLING, OTHERWISE IT'S NOT MUCH GOOD IN AN EMERGENCY. IF WOM
