Just to brag a little bit about the Swedish administration
I remember reading a lot of posts here about people waiting for weeks after their IVA to get the DVLA registration and be allowed to drive.
I took my last inspection on Friday (kind of a mix of your IVA and MOT). Car has been registered in the system straightly by the inspection centre, and my custom plates as well as my registration papers arrived today, so less than 2 working days after the inspection!
The weather forecast says it is going to be a bit sunny on the week-end, so I hope to have my first official and legal drive then
