Good thinking to related the question to the very basics of economics!
However, if I may say so, it sounds a bit as if you would like to emotional decision to buy a new Taycan with hindsight economics ;-)
What might (tremendously) affect the depreciation with EVs is technological advancements...
I switched from 20" to 21" summer tires.
Was quite surprised that the difference in range is super small. While the handling difference is significant.
The improvements are under the hood…and those changes are massive.
I probably won't switch but mostly b/ of the EU mandatory limitations & surveillance introduced last year.
First of all: congrats!
All modern EVs differentiate between a net and a gross battery capacity.
WIth the perf battery, net is 83,7 KWh on the Taycan.
100% means you charged to 83,7 KWh, not 100% of the gross 93,4 KWh.
(That's similar on other EVs, including the Tesla.)
There are various...
Not sure what you mean by "climate App".
The my Porsche app experiences severe problems since its migration to Azure, Porsche Germany said. They're working on it…
Glas roof is not a problem, we have 15 of them in the car park.
Innodrive is useless and creates problems.
Air suspension is a must have. 360° camera is useless.
Wouldn't say there's anything that specifically creates problems.
