I have been reading this thread with some interest as I am looking to join those if you who are lucky enough to already own a Series one, but I would love to make the one I buy C450 RGY as it belonged to a very good friend of mine. He sold it around 2001/2002 and it hasn’t been taxed since 2007. The owner kept up on the mot tests until 2010 which expired in 2011. I have not been able to find anything on it since that, so it may of died, or more hopefully, it’s been tucked away somewhere awaiting the day it gets found. Has anyone seen or heard anything of it in that time?
