That's worth knowing Byz. That means the cost of the MSVA will be balanced out by not having to pay for 3 MOTs!
My biggest concern is that I haven't got a single receipt for my trike parts. It's all second hand, bartered or home made. Do they ask for paperwork?
No receipts or Paperwork are needed if your parts are secondhand. It only really applies if you go for an age related plate and then you have to prove all the parts are new. Other than that receipts are only needed for proof of ownership but unless they have specific evidence that the donor vehicle was stolen at some point before you got it it will go through without any queries.
I provided no supporting documentation with the beach bastard. Not even the original logbook for the beetle and although it got delayed it was because they did not know what they were supposed to do.

That's now sorted and all my applications go via the head honcho at Theale.
Changes have been made to the process to to ensure you can get an inspection on site if required at the time of application! (By prior arrangement)
Hope that helps
