What about electric cars ? To purchase one may be expensive but after that the maintenance cost much less than a petrol car. Now I pay around $250/month (and I live close to the city) on fuel however, if I would have an electric car I would pay maximum $30/month which is a significant change. Obviously it is a new technology and we do not know how long it will last (battery) but this change is something that we might consider. In my case the break even point is 3. year. If I use longer than that the electric car then it was worth to buy it. What is your opinion ?
