I know I'm going to get a lot of "that doesn't mean anything" for this post. I know this is a vague "test" But... I did a comparison of a CPO vs a new 85 with the same features. Here is the CPO I used: 85 kWh Model S P36158 | Tesla Motors -- I chose this one because it was the cheapest 85 with relatively low miles (less than 5k) I went to the design studio and mocked up a car with the same features. The 85 CPO is for sale for: $67,000 The new 85 sells for: $85,000 (before tax credits) What does it mean? probably not much, unless you had a much larger sample size, but I don't have that kind of time.
