What would actually be fair (from a 60-owner perspective) is for the price of an upgrade from 40-to-60 to be on a linear sliding scale. To get it in Yr 1 $10,000, Yr 2 $8000, Yr3 $6000, Yr4 $4000 and anytime after the 5th year $2000. Likewise with the supercharger upgrade. These options become less valuable over time as the car depreciates.
