I have a 2016 Nissan Leaf. It's a short range commuter car, it makes a great second car for a family but it's no good if it's your only car.

I live in a left-hand drive country that gets heaps of used imports from Japan (who is also left-hand drive), so they are cheapish and easy to get YMMV,. The entertainment system is not touch screen, it has physical buttons including controls on the steering wheel. I'm not sure if it can phone home since it's no longer in a supported country. We use Bluetooth for music and that's it as the Nissan Connect stuff doesn't work here.

Don't know about your answer specially but can get EV conversion kits that provide the hardware to turn older cars into EVs. Of course you really have to know what you're doing or know someone who does and the kits themselves are often as expensive as mid range vehicles.

Those "cheap" Asian EV's look like bare bone vehicles. But you get what you are paying for.
For once I wouldn't suggest to buy an old first gen EV. They are unpredictable, and have a lot of different issues.

Fiat 500e first gen and Nissan volt first gen.

Pretty much it unless diy

I tried an VW ID3 this weekend, the software was low key, it mostly relied on you having Apple Car or it's android equivalent.

Just rented a KIA Niro and wouldn't have been able to tell it was an EV from the interior. HSS Bluetooth but I usually opt for Android auto.

The old Chevy Sparks are basically golf carts with 4 doors and permission to drive in the roads. They are the least "techy" EVs I've seen in person as they are really just a battery swap with the minimally-appointed ICE version of the car, which is very sparse on the electronic doodads.

Hopefully someday.

I think that this suggestion is a bit more extreme than what you're hoping for but the Carice tc2 is an all electric car with all the extras and features of a car from the 1960's
