Ok I will give you that, but I was talking in the context of the original OPs query in relation to a vehicle owned by them and they reside solely in the UK. That is officially what DVLA advise.macmedal, that just isn't true. If my friend from France brings over their French registered car, temporarily, within the Vienna Convention, and I am insured to drive it and it is taxed and registered correctly in France, I, if I were a UK resident, could drive it in the UK.
However perhaps you could even take it a step further. Say you had a second home in France and had bought, registered and insured a vehicle in France for use at that second home. If you wanted to drive into the UK temporarily with that foreign registered vehicle, for example to have it serviced. I think within the terms of the convention you would legally be able to do that as long as it was properly insured and it was for a temporary period. But I suppose this relies on the definition of UK residence, say you have dual residence 6 months in UK and 6 month in France.
Lots of technical grey areas which would take case law to clarify. The world has changed with a lot more movement within the EU. The DVLA and UK VCA seem slow to respond to this change and perhaps some of the information is a little misleading and confusing. But I am no lawyer so we have to go with what they currently advise.
