Personally, it sounds to me as if most of the $ is being spent on Maintenance items that are inevitable. The only thing that didn't was the ECU---How about the A/C? Does it ride well? Ask yourself this: If the car is for sale and you knew all that had been spent on it, would you feel fairly comfortable buying a 125,000 mile 11 year old GS 300. I've had 3 since '95.
