Based on the ongoing situation a family friend has, don't touch a Zoe. Short version is the dealer had his car longer than he did in the first year, he eventually had enough and tried to p/x it, the interest from any dealer was about as high as the Zoe's engine emissions. He then went with the rejection option as it had spent the majority of the first year of ownership in the dealers for various issues, Renault weren't interested. Up-shot is he is still paying for the thing even now and looking to go legal.
The car industry misdirects people with impressive MPG figures and VED as indications of what a car costs to run. and ignores depreciation, The first is an indication of the distance you can travel based on the amount of fuel used and the other is the amount you need to pay each year to have a car on the road, depreciation is reasonably predictable on existing models. For example my old petrol Fabia (38mpg) was cheaper to run per mile than my Leon Sport DSG (50mpg), once you included depreciation the Fabia was was even further ahead.
While this suggestion is unlikely to get much love on here, this thread started with discussion of a Zoe, so i'll assume anyone reading this has adjusted his or her expectations accordingly.
Consider a used Jap built petrol Yaris. After many years of messing about with VAG based diesels and telling myself that it was worth paying for the extra space that was rarely used and slightly nicer interior/ability to overtake comfortably, I eventually accepted and embraced the idea that a car for commuting is simply a tool to do a job. It has to be said that this is not a fun car to drive, however VVTI makes it slightly less boring than alternatives, cheap insurance, 50+mpg, tyres lasted around 6x longer than the Leon and cost less than half as much, discs and pads were similar and virtually nothing went wrong. Going petrol means no DPF regeneration/blocking or DMF failure to deal with, NA so no turbo failure, chain driven so no belt interval and simple to work on/service (read it takes about as long as a family Domino's order to arrive and costs the about the same) and it just kept going, owners are regularly seeing 2-300k from them without major issues. A decent low miler can be picked up for a few grand rather than 10k for a Zoe and the fuel cost will be only slightly higher each month than a Zoe's battery rental and cheaper once you allow for electricity.
