So ladies and gentleman, I finally received what seems like a definitive explanation from DVLA - it's a mistake by the DVLA.
Please see my web chat with DVLA below:

Hi sorry for the wait ive just had a response and apparently its an error on the v5c and a new v5c will be issued to you shortly with the correct information.

It's an error? Then I need to know immediately what the actual category of my vehicle is - how do I find this out?
9:39:04 AM
When I enter my registration plate into DVLA's online checker, it says the same thing, that it's a "Z1"

I cant get the information until its been updated on the vehicle record which will intern update the online checker, if you call the contact centre then an advisor should be able to get the information for you of what the correct definition will be when its updated..

So to be clear, all those who have purchased the same vehicle as me in December can have no idea at the moment what regulations may govern the taxing and legal use of their vehicles, without individually calling the number you've supplied?

As the error has occurred and been picked up all customers that have been incorrectly registered will receive new v5c documents with the correct vehicle category on them in due course this will not affect the use of the vehicle in the meantime.

Yes, but when we find out the reality in due course, our tax rates and the way in which we are able to use our vehicles may change?

Steven
without being able to check the record myself as I dont have access to the relevant systems, I can only advise to call for an advisor to check if there would be any change.

This is a terrible situation. Letters should be sent to every person who has purchased one of these hugely expensive vehicles immediately, clarifying the situation immediately. There will be potentially dozens of people out there, maybe more, who have no idea that they might soon be expecting to pay considerably more for the road fund licenses, or that they might be subjected to traffic restrictions.

I completely understand your concerns I would suggest to call to speak with an advisor who can then call the relevant department in regard to the error that has occured at the point of first registration of the vehicle.

So there you have it folks. I haven't time to call the number supplied and wait God knows how long for a reply today, but if anyone else who has a Z1 vehicle does get through - please could you post what they say on this thread? Thanks!
