We had one for three years (now returned - 21MY) and it was faultless, it cost us £400 (after tax on salary sacrifice) all in (so insurance, servicing, tyres, tax the works) which is a great deal hence we grabbed it. I suspect many of the 21MY cars for sale are these HSE ones with OY number plates

They can have issues, early cars had heater issues and there is a battery cell problem (covered under warranty for 8 years) which can occur.
The 12V battery on early cars can be a bit problematic to (but is not expensive and is easy to change).
Great to drive, and I mean really really good, not much close to it in the EV world.
They are a gen 1 400V system and hence max charge rate is just under 100A and not for the full charge cycle (not an issue for most usage).
We use to get circa 200 miles range in the winter and 240 miles in the summer but, it depends on driving style and top speed (blatting along country lanes is better than motorway cruising).
We were very close to getting another but, decided five cars was a bit excessive so didn't
