Do You Want to Buy an Electric Car?

Recently I have been thinking of buying an electric vehicle. Why? Because there are plenty of big cities around the world where is mandatory to pay congestion charges. For instance for diesel engines. Furthermore, it is good because it minimises global warming. But I have a lot of doubts about what is the best option.
In this one-hour chat, I want to discuss with all of you a few questions:
Is the best time to buy an electric car?
How much does it cost?
What about the security of this kind of vehicle?
is it easy to recharge the battery and where?
How many times per week or day?
...

I hope all of you can bring ideas or your own experience to shape a good decision.
