My 1990 LS 400 has just over 176,000 miles on it. The timing belt, including water pump, thermostat, pullies were just changed and at the same time I had the coolant hoses and drive belt replaced as well. Other than that, the wear and tear is mostly cosmetic. The driver side lock has loosend off and pushed into the door panel, so I must get that repaired. Otherwise the car is running smoothly with great ride. Just put new 225/60/15 tires on and that has made a huge difference with overall road manners.
