The reactions are mainly: €35k for a small car?? Are you nuts? A regular Corsa is 20k so come back when you achieve that!
That's penny-wise, pound-foolish!
What does that mean for the monthly cost?
Throw in lower maintenance and the advantage is around 10 cents/kWh.
But if you drive 30k a year your advantage is €3000/yr and the difference is paid back in just 5 years! And electric drives very nice...
But let's look at people driving a modest 15k km a year. Their advantage is €1500/yr.
For most of them, paying €15k with a payback time of around 10 years might be daunting.
Which is why we have tax incentives.
Or you could say you now save €500/yr in tax and €1500/yr in gas+maintenance. €2000/yr in total.
So your pay back period is now €15k/€2000=7.5 years.
That's an interest rate of 11%: not bad!
Assuming 40% income tax you would pay 22%×40%×€20k=€1750/yr for the regular Corsa and 7%×40%×€35k=€980/yr for the Corsa-e. So you save another ~€750/yr.
Your payback time is 15000/2750 or 5.5 years. That's an interest rate of 14% on the extra €15k!
And I would certainly try to drive it because the driving experience of an electric car is usually that of a more expensive fossil car.
And although second hand EVs are a good value for money, they are scarce and many 1st gen vehicles have limited range.
