My son is considering replacing his car and asked for my advice.
I told him that economically, it is always better to repair the one you own, rather than buy a new or used one - that you can do an awful lot of with the amount of money it costs to buy.
With 2 exceptions: Body damage (such as rust or accident damage) and difficult to diagnose electrical issues.
But there is the frustration factor and inconvenience factor, both of which weigh heavily in the decision. This depends on what your circumstances are (like having a spare car), and whether you do your own repairs - AND how much risk you are willing to accept.
Some folks (me included) will keep a car until something major breaks (engine, tranny, etc.), but some don’t want to even take that chance. Others replace a car every 3 or 4 years, so where the point is seems to be highly variable.
I’m interested in the thoughts of the community.
