2020 Toyota Prius - Maintenance Requirements

I intend to buy a used Prius. I have some health issues which will make regular car repairs or car maintenance very challenging. How do I choose the best (most reliable + energy efficient) car in the UK ?
I’m having confusion as different people say different cars are best from the above mentioned position.
Please guide

This is a Forum of mostly US members so what you have in the UK are mostly unknown to us. I myself would never buy a used complicated Hybrid of any model.

A Prius still requires regular maintenance for its gas engine.
