Instead of buying a car every few years we bought a better one with the aim of keeping it until we could no longer drive. It is now 20 years old, but still reliable, safe, and looking good. Not as economical as modern cars but very happy with my choice. And of course, it has has some repairs.
Our other good decision was to put as much as we could into our home and pensions by decorating ourselves, making own curtains, buying second hand and sprucing up, and so on. A decent pension took care of retirement.
There wasn't as much to spend money on while we were doing this, so no temptation to buy phones at £1000. No coffee shops, made own packed lunch, etc.
