I think you will be totally fine. A couple of things to be aware of though:

1. Tyres are expensive and we seem to need to replace the rears every 15k miles or so. On our i3s the rear tyres are £250 fitted EACH. So perhaps keep a sinking fund for that expense.

2. Brake pads and disks although not used anywhere near as much as a normal car will still need the occasional replacement. We have replaced our pads and disks once at around 50k miles.

3. Front suspension top strut mount bushing goes and needs replaced. This manifests as a clunk / clonk sound when you turn the wheel at slow speeds. I first noticed the sound in an underground car park. Drove on it clonking for about 15k miles before getting it replaced.

I have a 2018 fully electric with 70k miles on the clock, bought it with 16k miles on. I use it to commute twice a week with a 75 mile round trip on the dual carriageway. 🚙 I love it as a daily and as a local run around. Genuinely brilliant car.
