Can't you buy a banger, cut it up and weigh it in, and just sorn and insure it? Keep the vin plate and log book? Unless this is what your planning on doing and I have missed this!

I did this a couple of years ago when I scrapped a old discovery just so I got the full years ncb.

A insurance company wouldn't find out if you did that and I can't see any risks either.
