Sadly it is not that easy.

Yes you can get a car for under £200 per month for two years, but the reality is this.
Your deposit £3099.50
24 monthly payments £199.00
This is based on 7500 miles per year, after that it is 10p per mile.
Total spend £7875.50
(Current Nissan Offer, terms and conditions etc)

Remember you don't own the car and when you return it you could be liable for any damage to the car, (many years ago, I was a car salesman, Lythgoe Peugeot and others, before changing careers, so I do know what I am talking about)

Compared to my car, a large Diesel Estate, which is paid for and does an average 50 mpg and nearly has as much tech on it as a Leaf, I could drive, at current Diesel prices, 75,400 miles, As I tend to drive 15 to 20,000 miles per year there is no way I could ever justify an electric car, even a BMW i8.

Of course there are other things to take in to account, service costs, tyres, road tax, etc

I have no doubt that they have a place, but seeing there are Diesel cars out there that have 80mpg+, I cannot see a bright future for them.
