Purchase advice Family car

Hello! We (my wife and I) got offspring three months ago and would like to finally buy a car. The frequent car rental may be a bit cheaper, but it sucks incredibly and eats a lot of valuable family time. The following key points are: -budget: 800€ -Km per year: 5000km approximately, rather less -driving mode: Rather cozy and slow, do not need much PS profile: I don’t need the car to work, there are mainly family visits on weekends (mostly up to 100km per trip), weekend shopping and Baltic Sea holiday (once so 500km). -Place: stroller and travel bed, otherwise nothing extraordinary should be enough for a holiday with a child and another child (in the next 2 years) should still fit. -I don’t care about appearance, I don’t put much value on it. -Others: It’s important to me enough space and reliability, and as economical as possible. -City for possible suggestions: Braunschweig Since I didn’t have a car so far and have little idea, thank you for your help. Initial research revealed candidates like Ford Focus tournament or mondeo tournament. Kombi or Van? No idea honestly what makes sense. I hope you can help me
