The 3.0L is not an interference engine so you don't have to worry about valve damage. My daily driver is an '88 Grand Caravan with 379,000 miles. The timing belt has been replaced only once because the water pump was wobbling so badly I was measuring water usage by the mile instead of by the day!
I also have a '93 Dynasty with only 4,200 miles. When I plug in the smaller battery cable once every other year to drive the car, it starts fine but you can feel the idle is too low at stop signs. After coasting off one exit ramp, it is fine.
