Every thing else that you want falls under this category. A car, household electrical, electronic items, etc.
Exception is for the house as this falls under necessity.
I took the approach of running a company for these items. They have a lifetime and the funds readiness is directly tied to their useful lifetime. This is because I want an easy life. It is not worth it to clutter your life with problems created by these items.
Eg. A refrigerator in my home should run without any problem for 7 straight years. After the equipment hit its lifetime, I will consider to change it for a new one well before it create any problem. The item works for me instead of creating a problem for me. Easy life....
