According to the DVLA's website a white Jaguar 3.6 (the website doesn't specify the model) with that registration is actually taxed until the end of September...

Not sure why you'd want to leave an out-of-date tax disc in the window, but then I've never understood the tendency of some show goers to dress up, build stages, use cardboard to turn their cars into tacky imitation submarines, fill their (limited) boot space with camping gear, or put-up 'themed' stands.

Takes all sorts, I suppose.

Bryan, your car looks awesome as always.

Hi Bryan
Did an HPI check on that Reg number not recognised
DVLA shows not registered on SORN so should not be on the road
No wonder he did not want to talk to you about it.
