We've got that exact car but a 59 plate Took us to the Vendee in France last year with a roofbox + bike on top and 2 kids in the back
Fantastic drive, feels quick handles brilliantly and rides better than most German estates Has never let us down - done v long drives
Terrible on snow on the big wheels but sticks well in the wet
My Dad asked me this weekend if I had any choice of car what would I get and I honestly think it would be the S Max
Lot of Volvo in the car as well think its one of the safest cars made in any class too
Funny when we were looking test drove an A4, Merc C class estate and the Renault Grand Scenic - S Max was the best compromise by far
Your sister will miss it!
