Assume one had a SORN'd vehicle stored off road. The MOT expired a couple of years ago, and that's when it was SORN'd.
Now it's more or less ready to go back on the road after a huge amount of welding and suchlike, but it's possible that other work is also required - maybe a tyre or two and a brake pipe etc...
Now, if one wanted to bung it in for the MOT, to see what it fails on, to target ones resources to fix the right bits, is one allowed to drive it to and from a booked MOT while it's still SORN'd - bearing in mind that after the MOT it might continue to be SORN'd for another month or so while everything is fixed up? In fact it's possible it could be SORN'd for another 2 or 3 months after the MOT - depending on circumstances.
How near does the MOT station have to be? The one in our villages is famously staffed by fuckwits who fail everything (unless it's a vehicle they are selling and they seem to pass OK with no brakes) just to be bastards.
I'd like to take it to a garage opposite my workplace as they know this type of vehicle well and would likely be ideal to do any repairs I couldn't do - but they are 50 miles away - would driving it that far for a booked MOT be seen as taking the piss?
