I cannot understand Norwegian but I have here one Danish guy who has no problem with it;)
So he said that no-one here believes this car exists? It does. Driverside has door from 242 and other side has normal 244 doors. It has B210K under hood. Although you might think we are quit good here at making bread from crap ;) this car seems to be original. 244 doors have never been such in need that someone would go for moving B pillar to make room for longer 242 door.
You can see more pictures of this car in Volvo Club Estonia forum (Before; after )
It is just nowhere to find any information about this model, except this.
And of course Wikipedia ;)
I am not the owner but in case you know anything plausible, do not hesitate to share with us.
