Buying an electric car is very different from a petrol one. The entry price is expensive because of the batteries, but it is balanced by the low cost of the maintenance and energy :
70 euros = 10 000 Km.

Many countries offer financial helps to people buying an electrical car, check out.

With your familly car, you may burn 7 liters/100 km in sub-urban and urban transportation.
If you drive an average 60 km per day going to your office and back home, that means you drive 13 800 km each year, alone with your briefcase and you will burn 970 liters of petrol.
Considering the european prices, you should pay for this petrol from 1200 to 1300 euro each year.
With a Smera, that will only cost 95-105 euro.
5 years : 5000 euro at least, with the current petrol price…

I hope you will have soon the opportunity to see, try and buy a SMERA.
