Talk me out of buying this Panamera Turbo S Sport Turismo

I’m dangerously close to buying this:

2023 Panamera Turbo S E-Hybrid Sport Turismo. 16,500 miles, £97,750, private sale. Huge spec..PCCBs, Burmester, InnoDrive, night vision etc and apparently Porsche warranty through to December 2028? Is that transferable?

On paper it seems slightly ridiculous in the best possible way: 700+ bhp, proper V8, estate practicality, comfortable enough to use every day and probably one of the last cars of its kind.

The thing giving me pause is that it’s already had four previous owners despite only doing 16,500 miles.
That feels like a lot of people moving it on in a relatively short space of time. It could be completely innocent with this sort of car, but equally it makes me wonder whether there’s something about the ownership experience that looks much better on paper than it does in reality.

So: talk me out of it.

I’d particularly like to hear from people who’ve actually owned one:

Would four previous owners at this mileage worry you?

Is the hybrid system/battery likely to become an expensive headache?

Anything frightening lurking as these get older?

Are PCCBs something to be wary of at this mileage?

What is real-world depreciation likely to look like? Where is value today? Not much to go on price discovery wise..

Is it simply too big/heavy to enjoy properly on normal UK roads?

Any known issues I should be looking for?

Or, alternatively, tell me it’s absolutely fine. Presumably the four previous owners each enjoyed it so much they felt someone else ought to have a turn??
