The v70 is actually a Ford, that is, it was made after Ford bought out Volvo in 1999.
We drive a Volvo 960 1996. There is no way the Hatchback on our car is fiberglass, when the struts are broken, that door is super heavy. Our kids ride in the rear facing seat when they hit the right weight, 50lbs. They're really excited about it initially, but its actually pretty lonely. My kids are tall & thin, so middle dd was over 8 years old by the time she could finally ride back there. My youngest is really a skinny minny, so it'll be a while for her, she weighs just over 40lbs and rides in a Radian.
When ds was 8 he rode in the back across the country.
I will admit, that picture was alarming, but I know the original Volvo's are far safer than Ford's version.
