Ignore my previous post, the Stanza door trim is different to the 510

If the rear 1/4 vents are like those on the 510, they are held in by a four screws usually.
You need to rotate the vent as you extract it since the part inside the "C" pillar turns up to prevent water ingress.
The trim around the roof gutters usually just rolls of once you lift the leading edge.
It might be wise to lubricate the gutter side with some WD-40 to loosen up the grip on the body steel.
