Purchase advice Espace as 2nd car

Good morning, At the moment I own a Fabia Combi and often fight with the place. We have a son (9 months) who is still sitting in the car seat and this (a reboarder) also needs his place. The trunk is also not exactly the biggest. If my wife is on the road with the little one it just goes out (car Teutonia) however more often on weekends to your parents and also take some with me. Now I am looking for a used Espace I don’t know what I want to spend on the second car, but that’s all I have at the moment. On the internet there are a lot of models at this price but I really don’t know which one to look at 🙁 3.0 , 2.2 , 1.9, 2.0 Would be happy if you could help me a little bit more. Thank you !!!
