I'm sure as a tax exempt vehicle you still need the tax disc but dont have to pay for it.
It must have cost a fortune for the ads and they seem have to made a massive mistake
hmmm... seem to remember hearing something about cars that are over 25 years old being considered vintage and therefore being exempted (don't quote me on this though!!!)... I'm sure Ian Flemming created chitty more than 25 years ago, so I guess the tax inspectors screwed up again...LOL!!!
