I had both 86 240 & a 96 850 wagons that I loved. I "moved up" to a 02 V70 XC that I don't love. I've been looking for another 850, but I've come across a 97 V90. I researched the specs on the 850, V90 and 960, they're so much alike. Did they really have 3 wagon models in 97 with only slight differences? Anything I should know about the V90?
