Eilt! Find family carriages like Caddy

Servus together. The old woman’s car is now ready for the press or abroad. She wants something like the caddy now, because the stroller has to fit in and the 2 kids. Our budget is at a maximum of 8000 euros. Have we looked at a folk caddy with 1.6 engine. Does it do what? Because alternative there is only the Berlingo, Kangoo or the Doblo. But are they also good for what or prefer to go to the VW group because of long-lovefulness etc? And what should one pay attention to when buying with the caddy? (Known flaws etc.) After the Tüv is due since February, eats slowly. Hope you can help! Thanks and greeting Matthias
