Buying 2nd hand Model 3 Performance

[mudnomad]

I've decided I want Model 3 Performance and now I'm looking at various 2nd ones.
Could somebody please clarify:

Is this the maximum option for self driving?
Do all Performance models come with track mode and drift mode?
What is the difference in brakes between optional upgrade? Just bigger? 6 pistons Vs 4? Is it a big no if a car doesn't have the upgrade?
How much roughly is a full supercharger charge in the UK?
Does "standard connectivity" mean I need to use a hotspot for watching videos etc but all the other connected options like remote heating, summon etc will still work?

Thank you very much!

No, just means it’s capable of it.

How do I find out whether full self driving mode is activated? Where and what does it say?
