Other than the bongs of the original software, one of the main complaints is about rust along the seams & lack of wheel arch covers (you can buy these).
If you were to buy this car you’d be wanting to address the rust problems as soon as you get the car, same as if you intend to buy it from Motability in 3 years time.
It’s a cheap basic electric car & it’s doing a brilliant job of keeping other fossil/EV manufacturers honest at that end of the market (large discounts available on Peugeot/Citroen/Vauxhall EVs).
