If it is insured I believe you can drive it to the MOT station and home as long as it is BOOKED in.
Just what someone told me and I have always done it, try phoning the MOT station they will be alot more clued up.
Put the kettle on and stock up on biscuits, other than that just answer the couple of questions he asks sensibelly and it is over. No biggie.
Everyone has the right to own a shotgun.
Good luck
My brother inlaw makes number plates as a side thing. Feel free to pm me if you want a cheapy made up.
EDIT:
They are £7 each. Normally couple quid postage, or free if you live around here.
