What is CPO worth?

[auburnjosh]

How much more should one pay for a CPO 2016 S3 vs a non CPO used 2016 S3?

I'm looking at a:

2016 S3 PREMIUM PLUS PACKAGE **, **AUDI MMI NAVIGATION PLUS PACKAGE**, ** WI-FI **, **BLUETOOTH HANDS FREE PHONE & AUDIO**, ** I-POD READY **, **BACK UP CAMERA**, ** HEATED SEATS **, **AUDI CERTIFIED 100,000 MILE WARRANTY**, **19 PERORMANCE PACKAGE**, **LED HEADLIGHTS**, and **RED BRAKE CALIPERS**

This one has 11,400 miles and sticker is a little under $43k.

How much more would you pay for the peace of mind? It's basically extended warranty.
