The plate I got with my new bike last year suits me as well as any plate could, so I'd like to take it with me when I next get a bike. I can't find the answer to this on the DVLA site.

If my next bike was also new, I guess the dealers could simply ask the DVLA for a 2023 plate for the bike I was trading in, instead of one for the new bike?

If the next bike was used, how could I get a 2023 plate for the one I was selling?
