That is 60% of the cost of a new one.  It has probably been pretty much
trouble free at that stage.  If you can get another 60,000 miles from it
with no major expenses, it would be about the same cost per mile to own and
operate.  I think this model has a timing belt that will have to be changed
in another 20k miles or so.

I was surprised to see the KBB retail price in the 11k - 12k range.

One thing to consider is the financing. If you are paying cash, it may not
matter. If you are going to make payments, check out what rates you can get
on a new car.  Sometimes you can get a lower payment on a brand new car than
a used one.  Banks typically offer much higher rates on used cars.
