Rollovers and car weight

Lighter cars are easier to roll. Once the car rolls do lighter cars tend to perform better because the roof doesn’t have to support as much weight/force (I guess also the car has less energy do dispute since it weighs less)?
Do wagons do better because of the D pillar and possibly greater on roof stability as the car rolls? What about tiny 5 doors with a combo C/D pillar (no window behind the C pillar)? Is the nearly flat roof an advantage?
Are the traditionally safer cars like Saab/Volvo/MB significantly better in rollover performance? There is little rollover data available. It isn’t obvious that the pillars and roof may be stronger (based upon pillar size), but I suppose the steel could be much higher strength.
How much of a rollover or any accident is circumstance versus car design? I mean each car has strengths and weaknesses no matter what the design.
For Saab I found a rolled 9-5 http://www.youtube.com/watch?v=v5CybGEWlcM There is another rollover mentioned online, but the pics don’t load for that.
The XC-90 videos are impressive. http://www.metacafe.com/watch/393322/volvo_xc90_rollover/
