I would love a Tesla but would take the Mercedes without hesitation.
Where I live they don't have any facilities for recharging electric cars. The speed at this will happen will take longer than 5 years to implement.
The country doesn't have enough electricity to supply normal consumption and black outs are common. You would have a beautiful car parked off in the garage and it would be a total waste of time.
Ask me this question in 5 years time and it will be interesting to see what changes have been made to the infrastructure for electric cars. I am sure you will find a lot more models than just Tesla.
I would pick the Tesla because i love the environment. I want a conducive earth for my unborn kids and grand kids. An earth free from the effects of global warming and green house emissions.
My country faces challenges in shortage of electricity supply and blackouts are very common. Electric cars charging facilities are also impossible or difficult to access but one thing I believe in life is, you can overcome any challenge if you put your mind to it.
Some of the technologies we are enjoying today also faced a major challenge at a point in time.
This is no brainer.
# TESLA !
It will leave 99.9% MB's in the dust.
Those who never tested Tesla's torque personally, may not understand what I'm talking about
