Which compact car with high seating position and entry + good guarantee (automatic up to approx. 25k €)

Hello together, my mother has enormous problems with her knee and is very difficult with her current Ford Focus (2003) and above all with the manual transmission. I would like to give her a car / finance and surprise her with it. It is important here just as high a entrance and also a high sitting position and a good automatic transmission + gasoline, because little long distance and a lot of commuting traffic (daily approx. 30 km) and annually approx. 10,000 km driving performance. The brand is perfect no matter – it’s more important to have a good and long warranty so that it doesn’t have to worry about expensive repairs in the first few years. It has been driving accident-free for more than 20 years, so SF-classes don’t play a really significant role. New price with a maximum of 25,000 EUR. I always hit the Opel Meriva – but I personally only have my own experience with Japanese and VW and am not really sure about that. ieoption if possible).Thank you in advance for your tips and experiences. Greetings Jan
