Modern combo for approx. 15,000€

Good day dear purchase advisors! I need some help, especially to get an overview of my possibilities. Briefly to the situation: Finally finished with studies, sit in a safe job and earn enough well to think about a (new) car. I commute about 60km daily (driving community, so only about 2 weeks a month). The car should bring me and my partner to Italy or Spain again for a holiday, so I think that I already have about 10-12.000 km As soon as there will be offspring, a station wagon should come along. From the driving profile I am someone who drives 90% quietly in traffic, and wants to quickly overtake a truck on the country road. Now to the car itself: We have a rather modern car in mind, until now we only had old weighings and want something “schickes”, definitely with built-in Navi, like Android car. So far in mind we had the Ford Focus tournament (the MK4 is beautiful, abe r then a bit too expensive unfortunately) and also the Opel Astra Sports Tourer. But what are there still compact combos? Or does it recommend an older middle-class combo? Unfortunately, I don’t know too well about cars and therefore I don’t really have the marking on what you should pay special attention to (e.g. how many km are too much for a used one?) The budget would be as mentioned about 15,000€ (own financed), but it would also be possible to increase this amount a bit for the p I hope you can help me gain a reasonable overview of the possible vehicles. ..and forgive me for the long speech.
