I did a quick Google and the Renault list price was from £28,795. As for range I saw R110 and made the mistake of assuming it meant range, so apologies there. So the range I was way off on and thanks for pointing that out. Price shows from £26K on further research (£22.5K with govt grant), to be fair hardly puts it into the wow factor considering what you get. A Renault Clio is a similar size and costs £14K. According to Autotrader, after 3 years ownership a Zoe will fetch around £8.5 trade in, Clio about £4.5K. I understand you can get grants etc but over 3 - 5 years ownership the financials on a Zoe look worse, not better all things considered.
That £8.5k is for a battery lease version (which would have been about £6k cheaper to buy in the first place), the cheapest 3 year old battery owned 41kwh I can find is £15,800. Considering new they were going for £17-18k at one point (my "cash" price offer on Carwow was just under £18k), that's not bad.
Please don't take this personally but your own circumstances does not mean everyone is the same. For example if someone has a family and have £22-£23K to spend on a car a Zoe is not an ideal choice. Not if you consider for similar money a decent sized VW Tiguan is very viable and would be far more practical.
The running costs are going to be significantly higher on a Tiguan unless you're doing very low mileage (in which case back to the question, why are you spending so much on a new car? Unless the cost is irrelevant, in which case why are you driving a Tiguan?).
I know not everyone is in the same circumstances, and I've already said before in this thread that electric cars aren't for everyone, but you need to take the whole cost of ownership into account, not just the upfront cost.
For the 15k miles I do:
Zoe cost:
£21k - £16k = £5k depreciation
36 x £20 = £720 electricity
£93 + £134 + £93 = £320 servicing
Total for 3 years: £6,040
No idea of the depreciation for a Tiguan, but just the running costs alone are higher than the total cost of the Zoe over that period.
36 x £170 = £6,120 petrol
£184 + £354 + £184 = £722 servicing
It may be more practical* but obviously you pay for that!
