It is true that most of the services on the maintenance schedule are recommended for intervals involving both mileage and time, whichever comes first. But the car you are referring to had 124K miles and was 18 years old, and most of the items you list are not scheduled maintenance. Those other items you had repaired either are not likely to be needed on an 8-year-old car with only 20K miles, or can be checked and only repaired if needed.Having just recently bought an NSX (1995 with 125k miles) that passed PPI with flying colors, there is still a ton of maintenance to be done just due to the age of the car even if the mileage is low. The $5-10k in immediate repairs is a real thing. I just recently had a ton of service done to get things up to par, including a lot of the things Shawn mentioned.
That's why I recommended having the car gone over by an experienced NSX mechanic, who can recognize what actually does need doing. Many repairs are far more likely to be needed after 124K miles and 18 years than after 20K miles and 8 years.
