I've had 4 cars with the 3.5 engine and never had a premature belt problem. Its a very heavy duty belt so I believe if there is a problem its going to be the water pump or belt tension pulley. There is a recomended 100k replacement recomendation on these belts but I had 110k on my 300m with no issues.
