Just to clear any questions up. . .
I repaired the car to a road worthy condition
Insured it
Drove it to and from its MOT ( legal if pre booked taxed or not )
Vic checked it ( again legally can be driven when pre booked taxed or not aslong as Mot'ed )
Tax'ed it at local DVLA due to having no documents as its Cat C, did that journey on the way home from the VIC check
Hope this helps
