Well, if you fall within the mileage category per week, there's no reason at all why it should not suit you.
Ratter15's point is not an issue as a Leaf with the 30kwh battery takes only around 15 hours to charge from zero. The 24kwh hour battery takes 12 hours to charge from zero. Extrapolating has shown that even if there was a 100% takeup of this vehicle in the UK, The National Grid could cope. Furthermore, when you take into account that no vehicle is ever likely to have zero charge (unless the owner is really foolish during use), it's even less of a load on the National Grid.
Beware of one thing though. The battery in virtually all electric vehicles is leased to the vehicle owner. It's never owned by the vehicle owner. Check carefully what this means financially when the battery needs replacing either routinely or through a fault.
For me a bigger issue is the electricity suppliers proposal to increase the kwh cost during periods of high demands - put the kettle on at your peril during TV adverts!
