Reliable service car up to max. 450€ /

Hello the round, I am looking for a reliable vehicle up to 450€. In the month I drive about 1500 km in the service, in addition would then possibly still private ways come. Criteria: – Not too slow (do not have to be 170 hp, but also no 32 hp) – as economical as possible in consumption and maintenance – Comfortable – Reliable – Climate – Not too old – Automatic would be great, but no absolute condition – Petrol / Diesel (?) -> I ask you this: Living and working rural (no change) What are the advantages, or would be recommended? I have already looked and found something like Ford Focus/Fiesta, VW Fox etc. and am a little unsure, because the car in particular can withstand the mileage and not all 500 meters should be brought into the workshop. At the price I would prefer 4000€, also very much among them. The indicated 450€ in the subject line are to be understood as absolute maximum. I look forward to your help, maybe you still have tips and suggestions. Thank you and kind greetings!
