Hi Roddy,

There are loads of really good EVs on the market for within your budget and the SUV shape you want. Finding one that doesn't rely too much on its touchscreen is the bigger challenge, but not impossible. They all have plenty of performance and will prove to be cheaper to run than your diesel car so long as you charge them up at home - and preferably at night on a cheaper rate of electricity. 

If you wanted to stick with Hyundai, both the new Kona Electric and Ioniq 5 are within budget and they have a sensible mix of physical switchgear. The Ioniq 5 doesn't really look like an SUV and not everyone loves its distinctive styling, but the Kona is quite in line with the Tucson. For your budget you'd be able to get quite a high-spec version.

The other car that comes to mind is the Toyota bZ4X. Aside from the odd name it's one of the more conventional electric SUVs on the market in terms of its cabin layout, so that might appeal. It's also remarkably quiet and civilised. It's not the most efficient, but that isn't a major issue given your low mileage. 

Another to consider is the Nissan Ariya. It's a really high-quality car and very spacious. Recent price drops have made it even more affordable, too, so a couple of different models are within budget. 

I highly recommend you go and arrange to test drive as many of these as you have time to for yourself.

In terms of residual value in three years, while I can't pretend to know the future, I feel the EV market will have matured significantly by then and residual values will have stabilised before that. The recent turmoil began with significant price drops of new EVs across the board, and there isn't any scope for that to happen again. 

Best of luck with your purchase, whatever you decide to go for
