Ditto.
Where some cars have a little bracket that holds up the dash, the Golf III has a fabricated beast that weighs 15 pounds and runs between hefty bolts in the door jams. The downtubes of the cage are outside of that structure - in notches, actually - so it comes into play immediately if there's a side impact. The firewall is also way heftier than on a lot of typical cars that end up getting IT'd.
