Have an 1998 ES 300 with 524,000 miles on it. I am the original owner from the showroom with 22 miles on it. My maintenance list is not as long as yours, but there are always some items that could use repair. Next on the list is new exhaust from the Cat on back.
What a great car! Drive it about 170 miles R/T to work, 5 days a week. Always runs good, and mileage between 28 and 29 mpg.
