Bad news! I was getting them mixed up. The GTN doors open really wide but don't stay open. The S5 doors stay open!
easily done, thanks for checking Shooter!
A bit of useless information but during mid to late production on the series1 Charles got a wet leg so they fitted the very thin rain channel to the wing panel where the door meets,our car is the wet leg version. Getting in and out is a bit of a faff especially with my wife's dodgy knee but hey ho were all getting older Volvos post is spot on.
That is interesting, do you have a picture by any chance?
