I’ll be interested to see how your trip to Wales goes, as range especially in winter is my biggest barrier with frequent longer journeys. Do remember in many areas its now 20mph and maybe quicker to park your car at the border and wal . I know this because I bloody live their however its not yet being enforced by go safe money making vans!
If the BYD Seal were to join, preferably in awd guise or the EV6 is at a realistic AP, I may take the plunge, like yo I have use of another car. TBHI nearly went for the Ioniq 6 but finding parking spaces in our small town 5m in length can be difficult, plus we take the daughter Blackpool every year etc. Failing that PHEV or Hybrid.
Its a shame mate that your brilliantly written thread has been ignored by EV enthusiasts or anyone looking for an ID in particular.
