Because a P85 is always a better buy than a S60, in every circumstance? So let's discount mileage (even though 25K miles is not insignificant...) and just line them up for now.
Tale of the tape
- P85 vs. S60 - this one shouldn't be close.
- Vin 17496 vs. Vin 44916 - these build dates are about 11 months apart. Fremont improves 20-30 parts or processes every week. This is not an insignificant consideration.
- Silver vs. solid White - the most subjective choice, but white - not Pearl W but just solid W - outpolls silver in the Deliver Tracker by a wide margin (better than 2:1 several quarters)
- body color vs. pano - about 1:4 or 1:5 is the common ratio here. Pano is a big part of the Model S identity IMO.
- same wheels, same performance leather - PUSH
- CF décor & CF spoiler vs. Piano black & matching yacht floor - edge P85
- Active Air (not SAS) vs. UHFS - PUSH
- The last two are apples vs. oranges but that's the problem with comparing apples and oranges
So it's a pretty bare bones P85 vs. an adequate S60 (though actually items like MYF & UHFS are super rare in 60s.) I dunno, doesn't seem crazy they are in the same strata.
At the end of the day, I feel like we don't have to right metrics and data points to evaluate the CPO yet, though. Like we should, by now, have figured out some rough guidelines along the lines of:
List price of this P85 = 96,470 - [{-600 x 23 months} + {-.60 x 34598 miles}] = 61911.20
List price of this S60 = 74,570 - [{-600 x 12 months} + {-.60 x 9116miles}] = 61900.40
(hypothetical list & depreciation factors, for illustrative purposes only)
I'm not suggesting depreciation rates of $600 per month or $0.60 per mile are the benchmark; I am merely pointing out that a proper methodology would use this kind of quantitative approach.
