That's a fascinating and informative discussion. I currently have a Skoda Octavia VRS diesel, bought from new but now six years old with about 113,000kms on the clock. Diesel is currently 1.29€ a litre here (£1.12) and I get about 60mpg.
I'd have another in a heartbeat, it's the best car I've ever had, but I'm feeling my environmental responsibility weighing on me, so my current plan is to replace it in two or three years time with full electric. If I do that, I'd install solar panels and a charging point on the house at the same time. Lots of free Spanish sunshine.
I'm hoping EV technology will have moved on a bit more by then and prices will have come down a bit. I'll probably stick with Skoda because I love everything about them. The furthest I go these days as a retiree is Alicante or Valencia airports, both around a 240km round trip. The rest is pottering. We haven't driven back to the UK for a couple of years because flying is so much cheaper, but I'd like the option. The idea of driving across half of Spain, the whole of France, crossing the channel and driving Portsmouth to S Wales in electric makes me nervous! Have ferry companies got charging facilities for EVs in cross channel ferries yet? They are missing a trick if not.
