Thanks for the info Ash,
Strange array of estimates and actual values achieved and as an 'old un' it's certainly looking like some of the older mundane Brit stuff is not performing particularly well. As a Wing owner I spied that hideous 97 1500 with a skip load of shite added to it. Checked the catalogue and stuck the reg number in to find a 'very interesting' set of speedo readings over 15 years! Up to 70k, down to 4k, up to 20+ down again, then up again! Great care needed as a buyer.
This is the site I now use for tax/mot checks - all in one place better than DVLA.
