Well, I tend to buy private party Japanese cars with 100k miles for 1/4 their original price, and drive them for the second half of their life. We’re at 209k and 163k right now with no significant breakdowns in a looong time. Last car made it to 222k.
But it depends on what your car is for. In my case, just to get me reliably from A to B with my crap. I’ll put the money we’ve saved into the downpayment late next year 🙂
