Half-way “reasonable” car (consumption vs. insurance vs. fun)

Hello ! I just have a difficult “problem” to solve. Since it is no longer worth making my old E30 TÜV-ready (August), a new car must be here for me and my girlfriend. At our disposal we have 600€. The car should meet the following criteria: 1.) as economical as possible in consumption and in insurance 2.) no small car (Yaris, C1, A2 and Co. fall out…) 3.) a little more horsepower, 100 would be optimal (85-90 but also OK) 4.) qualitatively i.e. little repair prone 5.) K Lima system would be great I know, points 1 and 2/3 contradict each other at the first moment, but that’s exactly the crux 😉 It’s supposed to be a good compromise. “dream cars” would be my girlfriend: – Audi A3 – Alfa 147 Point 1 doesn’t fit with the Alfa, besides, the quality should not be so sparkling. The A3 1.6l is as expensive as I thought, kema therefore in question. However, for max. 600€ you usually get only old models (2000) with some kM. Whether that makes sense ? yet something in the Toyota Corolla direction, whereby I don’t like the models you get for the money at all 🙁 Does anyone have another hot tip ? Greeting Sven
