When discussing 960's I believe there are 3 basic issues.

1) The early ones have the same wonderfull smooth 6 as the later except that the timing belt needs changing more often. This is a "cinch" and took me less than 2 hours on mine the first time. Next time should be down to 1.5 hours. There is no excuse to be worrying about the belt, just change the sucker. The wagons still have the solid rear axel as the first multilink design doesn't fit.

2) The '95's were a transition year with the improved suspension, A LOT IMPROVED, and the multilink is now on the wagons, but it has many ECU, exhaust, etc. revisions that only lasted that year.

3) From '96 on the 960 and S/V90's had no significant changes and the design was pretty well debugged in almost every respect. (Except for the intake manifild gasket.)
