Used cars up to 700€

Hello, because I don’t have so much idea about cars, I ask for a little help. I have read myself extensively, but the more I read the more helpless I become My father is ill and would like to buy a car so that I can visit him easier. The budget is up to 700€. The following basic data: – In everyday life I don’t need the car. I would drive about 800km/month, primarily long distance/motorway. – A German car would be important, as this I’m quite happy to be seen professionally (if I’m going to the meeting). – Adequately large interior, as I’m 1.90m tall. – Possible not repairable (quick career entry after studying). – 5-door (personal preference) – Sufficient PS to drive comfortably in the range 130-150km/h and also overtaking. I looked around for Golf, Audi and BMW. However, if I google the models on offer, almost always come horror messages (1.4 TSI / 1.4 TFSI). Here’s a little bit more choice of potential candidates, alternative proposals I would like to listen to: BMW 318i 129PS 2006 141,000 KMhttps://tinyurl.com/yaexlcg2 Audi A3 1.4 TFSI 125PS 2009 138,000 KMhttps://tinyurl.com/y7vlfu5u Volkswagen Golf V 1.4 TSI 122PS 83.570 KMhttps://tinyurl.com/yaeqpvkd An alternative would possibly still be an Opel Astra, where I do not like the interior. I would be very pleased about opinions and tips, I hope everything is so legible and understandable.
