This should be done at 100K the car will need a "nose job" meaning they will remove the front bumper to access the belt and at the same time will suggest replacing the water pupmp and seals because it is so easy to do..
The Manual recommends timing belt replacement at 105K but you are now dealing with time because rubber will deteriorate I would recommend inspecting the condition of the belt for cracks and contamination from oil or coolant. Always replace water pump, thermostat, tensioner, and all rollers. These parts may look good now but will they go another 75K. Use only quality parts or you will be doing it again soon. Many aftermarket water pump only last 30K before leaking or even worse, coming apart.
