We can agree to disagree whether it is a wise investment or not – but I also take care to maintain my home, since the total cost of ownership is far higher if things like furnace filters, cleaning gutters, taking care of water leaks, etc, are ignored.  I think, too, that our driving habits are very different.  12k/year is about my average, mostly city. I assume from your 60k/yr figure that you are driving the freeways more often than not – which is much kinder to the oil.
