I was checking out a friends van that got hit here (parts are gonna be expensive to get shipped here, btw) and saw a XC70 at the same shop that got hit pretty bad. If I go back, I'll take some photos.
Anyhow, it looks as if it were T-boned by a passenger car (or other vehicle with a low bumper) at moderate speed from the left. Pretty square hit, with the impact zone stretching from the aft edge of the driver's door, across the rear door, and back to the rear tire. The impact apparently sent the Volvo into a telephone/utility pole, hitting it just behind the rear right door.
Curtains and front side airbags were deployed, not front bags. Minor intrusion of soft panels into the rear seat area, but no sharp edges. No intrusion into the front seating area or the cargo area where the 3d seat would be (there wasn't one installed). Can't remember, but I think both door windows were shattered, as well as the right rear cargo area window. Glass "pebbles" scattered across the passenger compartment.
Like I said, if I go back, I'll take some pics and post them.
