the strikers inward on all four doors in that thing, and it actually began speaking German! Seriously - the body felt tighter, the suspension respo nded more readily to both the road and my inputs. It felt more like an Aut obahn burner than a cushy Detroit rolling library.

glass for total rigidity??
Short answer, yes. That's why pretty much all recently built cars use glue d-in glass rather than the old style rope-in gaskets. It's not because the y're deliberately trying to make it more difficult for a DIYer, that's just a side effect.
