Focus for approx. 600€ Purchase recommendation

Hi guys, I’ve been driving Ford Escort so far but since the rust has now defeated my poor Essi and I don’t get a TÜV anymore I need a new one. It should be as young as possible, should run for a long time. Besides, it should already have some performance, I don’t know the focus at all. With what can you have some fun? Is this to be paid? Budget: approx. up to 700€, is searched in the area Heilbronn/Stuttgart. Here are a few questions: 1. Which performance brings I don’t want to exaggerate it but he should pull well. 2. Which model would you recommend? 3. What kind of equipment? I don’t need Supercomfort 4. What is to be considered at the Focusl? – Rust? – Running performance? – any special things 5. What kind of mileage is possible with good care? is there already experience-worthy? It’s just as I need a relatiev new, reliable car. It doesn’t have to be a tuner, it doesn’t have to be a 4/5 doorr. must last a long time with good care of course. I would be super grateful for a few answers. Greetings Chris
