Chopping up a donor

[ozz]

I was thinking that it might be easier to scrap my donor once the bits were off to avoid all the trouble of the scrapman (sorry person) not wanting to take it away without the paper work.

As I understand it I'd have to register with a Q plate and not an age related plate if I did this.

I can't think of what is wrong with having a Q plate?

I believe that the date of manufacture for tax purposes will be the date of the SVA so an age related plate would not give a tax advantage.

The requirement for a CAT is determined at SVA which is before registration (I think).

Have I missed something obvious?

What are everyone else's opinions on whether an age related is better than a Q?
