Thanks Lads, as always, more questions from the answers :)
I assume you only need the one SVA on original import of the vehicle and then you can have 'normal' MOT's thereafter.
What isnt clear is what documentation you would need if buying an imported vehicle in a private sale.
Does the owner need the original 'pass' for the SVA??
What else needs to be handed over??
Is it the usual V5 from DVLA??
Looks like a bit of a nightmare
