We have an older Sharan, its great. I love the flexibility of the seats. We have only had it a few months, its my car, DH has a picasso but thats no longer big enough now we have 4.
The way we use it at the moment is with the passenger side seat in the middle row removed. That way I can get in and fasten all four kids in in relative comfort and stow baggage without messing with the boot. If we have a visitor, I just put the other seat back in. They are really easy to take in and out once you have the knack.
I just hope it keeps going as its old, but in very good nick for its age.
