I never thought I’d be this way until I sold the car I planned to keep forever. It didn’t hurt as bad as I thought, but, I realized all that money was spent for them now that the car wasn't mine. I’ve also seen the stupid drivers that hit well maintained cars. Not worth it anymore.OMG, I don't even replace anymore the belts, hoses, spark plugs or ignition parts unless they fail early. And I only do repairs as needed. Even when approaching 150K-170K miles unless I plan on keep the vehicle past that point.
I used to do GOBS of maintenance on my vehicles because I planned on keeping them forever e.g., 300K miles. So, I did the maintenance base on that-starting from the time that the vehicle entered my possession whether it is new or used.
Now, I am getting rid of vehicles just past their warranty while doing a few repairs in the process as required. And as I get even older, I am ready to give them the BOOT while they're still under some warranty to at least get some money for them without having to shell out too much money just before they leave my ownership. They're just getting too expensive to keep around unless you do ALL OF YOUR OWN REPAIRS...in which I do!
I drive it until I get bored, or it costs too much to keep rather than plan on 300,000 miles.
