I did loads of pretty much trouble free miles in my Grand Picasso – which, if you compare to the Peugeot is the same car, just tarted up differently – the seats and interior plastics are virtually identical.
However, there is no comparison between them and my S-Max, the Peugeot/Citoren is soft, but bump thump on the road and thats mostly down to the Peugeot using cheaper torsion beam rear suspension & weird spring rates that give a soft, yet harsh ride. The S-Max is supple, rarely harsh and well weighted for a big barge.
I’d not go back, and would opt for a Tarraco/Kodiaq/Allspace if you needed a 7 seat SUV (not exactly a lot of choice here on Motability).
In life, it's not who you know that's important, it's how your wife found out.
