We have bought certified 2 year old used Toyotas with under 20K miles from both Carmax and a "no haggle, price posted" dealer that has many locations on the east coast. In both cases the prices were below book value and the cars have lasted very well. I use their posted prices to measure against other locations.
I may give myself a car as a retirement "present", and will likely stick with a used 2 year old car again.
