The main thing to know is that you must replace the timing belt and it's idler pulley at around 105k miles. It is customary (and wise) to also replace the water pump at the same time. If the timing belt breaks, it could cause very expensive engine damage, so don't skip the timing belt change.

There are several smaller things that may go wrong on the way to 100k miles - one of the most likely is failure of the transmission input and output speed sensors (goes onto limp mode - stuck in 2nd gear; if speedometer also does not work, then it's the output sensor) - sensors are about $20 each, 15 minutes DIY job to replace. Other weak points are window lift motors, window glass coming loose from the window lifts, and door lock solenoids. Radiator fan motors also do wear out prior to 100k miles.

Otherwise do regular checking and maintenance on brakes and tires, change coolant (use *only* G-05) and thermostat, and replace the transmission fluid (use *only* ATF+4) and filter at least once. Both accessory belts and idler pulleys should be checked and replaced when needed (the pulley bearings do go bad).
