Been up in footballer country - Alderley Edge and Wilmslow in the +8. Saw a Cullinan and Aston on interesting plates. I looked them up on the DVLA is my car taxed website, both were taxed but neither according to the online records are on the make of car I spotted. !!
There used to be a facility to report a suspected untaxed vehicle online, it had a notes section to state where last seen, perhaps you could pop the details in there & give it a try
When paper tax discs disappeared, we used to get lots of cars parking up an un-adopted road near work that were clearly being used, I used to report them and surprisingly the DVLA man and a van did occasionally clamp one or two
