Written off Model 3 potential purchase

Hi all. I’m looking at a Cat S car and just wondered if Tesla still allow supercharging on written off cars? I hear rumours that they do and some that say they don’t.

Also what happens to the warranty? Is it automatically void?

Should I walk away? 2021 performance for £21k with 40k miles.

Answer is:

Warranty void
Supercharging still good
