Thanks for the links, especially for relating the monk / minister parable to the other articles. And yes, the 50-something thousand dollar threshold for the car test is way high for this audience. The last car I bought was brand new (probably not the best decision), but at $15,000 out the door it falls far short of the numbers in their article.
Regarding the rooms used daily in the house test, I came up with 6 out of 9 used everyday (if bathrooms are included). I didn't count the garage or back patio. Regardless, it's fun to think about these things from a different angle.
