Having recently been taken out for a spin in a Tesla, I can honestly say that I've been converted from a complete 'nay sayer' to an 'understander'.
However, for me, the numbers/savings just don't stack up.
I do about 10,000K a year in my little secondhand Corsa. I tend to replace every three years, at a cost of around £1000. It does about 43mpg, so fuel cost are around £1,300 a year. If I factor in tax, and purchase price, then it's around £1800 a year running costs.
An equivalent sized Nissan Leaf, costs about 4.1p per mile - so I'd save about £800 a year in fuel, and possible £200 in tax. £1000 in total.
Factor in the greatly increased cost of a second hand Leaf (2014 at around £8K) and it would take me about 6 years before I started seeing any savings, and by that time I'd probably need to replace the batteries.
