grand picasso, berlingo3 or C8 ?

Hello, as our third child announces, we need a bigger car. We have to accommodate 3 children’s seats and have limited ourselves to C4 Grand Picasso, C8 or the new Berlingo. We drive by car into the holiday home holiday, so space for luggage for 5 people should be available. Which of the three vehicles above can you recommend? I have listed our Pros/Cons and hope for addition (e.g. maintenance, experience, safety, consumption values etc. Reperatura Thank you and greeting Frank Berlingo possibly too little comfortable, suitcases too small, only 5 seats, sliding doors, cheap purchase, little frills, children’s diseases?) Grand PicassoCoffe room too small for 2+3, children’s diseases?, no sliding doors, more comfortable and chic, max 7 seats C8 (or prefer Peugeot 807?) still expensive, “old” model, high maintenance costs? sliding doors, lots of space
