BYD Seal - Pre-Purchase Questions

Hi,

I am looking at getting a Seal here in the UK, but I've got some questions that I'm struggling to find an answer for, so I am looking for help here.

1. What is the car like to service in the UK? Are there a lot of garages that can work on your car for an MOT, accident repair, servicing etc?
2. What is the service schedule like? I currently own a Tesla Model 3 and the car never needs servicing, so I am wondering if BYD is the same.
3. The ADAS is heavily reported as being problematic. Have the issues been resolved with the latest updates or are there still problems? If so, what problems do people still have?
4. Has the onboard software improved to the extent that we can now create shortcuts for things like memory seat profiles or other such items?
5. I see the new Seal has been released in China, does anyone have any idea when the UK will see that edition released? I feel waiting a few months might be the prudent thing to do.
6. I heard that the front camera can now be used as a dashcam, but you need to download an app onto the car's OS. Is this true?
