Ex wife has had a xc-(not sure if 70 or 90) for seven years. It's a great wagon.
I've driven it a bunch and loved it.
They aren't cheap but drive very well especially in snow and rain.
The interior is also very nice.
She has had no maint. issues besides the normal brakes etc.
Her's is a model year 2000 which was bought new.
I think the one draw back is you have to use premium gas.
