In reply to your request.
Do you have a currant id card. Assuming you do you will have to get another No. from the immigration office. This is because the registration office computer does not recognise the No. on our id card and this allows them to get into the computer in Sofia and check everything. Not a problem, very simple 2lv.
When you have this, back to registration.
I don't think they checked the MOT but i took it anyway.
They checked engine No. and chassis No.
Took old plates off put new ones on
