I'm looking at 2014 and 2015 Model S 85 CPO listings and the prices and milage are all over the place. Do 2014's really have a better reliability record than the 2015's, like Consumer Reports wrote? Can you tell something about when the car was produced during the model year from the serial number within the VIN? Do the serial numbers run continuously through the different model years? Some cars have milage in the teen thousands. Do people really trade in a car with such low milage just to get the AP 2.0, or could there be something else going on with those low milage cars? Have you all noticed that the CPO listings for 85D models show the milage range at 65 mph, rather than EPA as they do with the rear wheel 85's? It makes the difference 30 miles rather than what is probably around 10 miles if it were an apples to apples comparison.
