Aside from the things already mentioned, its important to note that "HV parts" isn't always an intuitive category.
For example, the charge port isn't a HV part, since it isn't energized by the car and requires no special skills to replace it. This is useful, since its also one of the most likely parts to take physical damage.
A lot of the other wear items are suspension related and are pretty conventional parts.
And, of course, there's a vibrant aftermarket of used parts for Tesla in general, so even HV parts are not necessarily hard to come by.
