Search very reliable diesel up to 10,000,-€

Hello together, first of all a big praise to this great forum. I have been reading with you for a long time, and I have received many good tips and suggestions from this forum!! My Skoda Fabia 1.9 SDI with 350,000 km unfortunately does not make it through the TÜV, without which the costs remain in proportion. I would like to buy a car that should meet the following criteria: -Diesel (daily working distance 30 km, i.e. 60km total) -First of all I drive alone, on the weekend my wife drives mi t, and our little son. So a stroller should come in, which I am currently also getting into the Skoda Fabia Limousine (BJ 2003) -very reliable (I tend to Toyota/Mazda) Which models/engines are recommended here? -What alternatives are there? -The maintenance costs should be within the frame/average -I drive 95% country road -I want to keep the car the next 6-8 years I’m looking forward to your tips! Thank you!
