Reliable car wanted for long distances up to 800€?

Hello everyone! I am looking for a suitable car and since it will be my first car purchase, I would like to get some support in this regard! To the Hardfacts: I would use the car primarily for long distances (Germany-Austria, Austria – Hungary, Austria – Italy, Austria – Croatia) It should not cost more than 800€, maximum 850€ petrol would be important to me, automatic transmission also, air conditioning of course I drive since 2011 car, am unfa llfree and safe driving I want it to be reliable and as new as it goes for the price Now the question arises which models can be considered here! And I hope for your expert answers 🙂 My father is thoroughbred BMWler and for him nothing else comes into question – but I really don’t care about the brand, mainly it drives long and well! Thank you so much and love greetings from Vienna!
