To those who are buying CPO cars, is Tesla disclosing the reduction in charge rate? I would think that would be legally important and something Tesla would have to do, since Tesla are the ones who made an active decision to throttle back the charging and have data on every vehicle in the fleet.
I would not buy a CPO Tesla without Tesla stating two things in writing: Maximum range of that particular vehicle at 100% SOC, and how much the supercharging rate has been reduced from new. If Tesla cannot provide those two data points, I would not buy the car.
Something else to be aware of... Tesla is capping batteries at a lower capacity due to a potential safety issue, removing significant amounts of range. When Tesla receives such a vehicle as trade-in, Tesla rebadges the car to a smaller battery size when it resells as CPO. A car originally sold as an 85 may be rebadged to a 75 or even 60 depending on how much the battery was capped. However, Tesla does not disclose this fact at the time of purchase or the fact that those customers may be purchasing a battery with a latent defect.
